The Comfee Toaster Oven (CFO-BB101) and the Oster French Door Digital Convection Toaster Oven (TSSTTVFDDG) are truly polar opposites in terms of their sizes. The former has the smallest footprint while the latter has the largest cooking chamber in our roster. Their sizes are in correlation with their scores but are not the direct causation.

Exterior-wise, each has a unique feature—the Comfee has a detachable crumb tray and the Oster has a french door. Interior-wise, however, the small Comfee lacks the convection system, lighting, and number of heating elements that the Oster has.

The worst part about both of their designs is the build quality. The Oster’s french door can slam shut if you slip and the flat buttons usually require a lot of force to register. Nonetheless, its control panel is still easier to use than the Comfee’s not-so-precise analog dials. The Oster’s large cooking chamber had so much space to minimize potential messes, which wasn’t the case with the Comfee.

Due to the Comfee’s low power output and lack of convection, it performed below average in terms of toasting bread and baking pizza and fries. It had a decent score in roasting chicken though.

The Oster was slightly above average in toasting bread and breaking pizza. It was able to maintain a good temperature and convection setting to score quite high in roasting chicken. However, that wasn’t the case when baking fries, resulting in a below-average score.

It was difficult to perform our Toast test on the Comfee as we couldn’t input the exact cooking time or toast level. This was because the timer for toast was a countdown from 10 minutes without any level or minute indicator.

Our first attempt was 4m 10s, but the toast turned too dark, especially on the bottom side. Then we tried 2m 45s, but it barely acquired any color and we figured out that 3m 30s was possibly the best choice.

However, after many attempts, we couldn’t set the timer exactly as mentioned above and had to evaluate the result of 3m 50s. This strongly affected the oven’s toast score, resulting in a 4.6/10.

After setting it at 3m 50s, the Comfee produced four slices of toast with a golden brown color on the top. However, most of the bottom surface had no color but also just a few dark areas, so it got a 6/10.

The first batch, which was slightly crispy, was passable and our head chef Tuyet Pham gave it a 5.5/10 for taste.

The fact that we couldn’t set an exact timer only worsened the results for the second batch. The top had a large burnt area, the bottom had almost no color, and the toast didn’t become crispy at all. This result made the Comfee fail the consecutive usability section of our toast test and got a 2/10.

We began our Toast test on the Oster with the default toast level 4 and got pretty good results right off the bat. For good measure, we continued to try the toast level 3, which failed to color evenly within the stipulated time.

We then tried level 5 only to end up with burnt toast and not the expected deep brown shade. Regretfully, while level 4 was the best toast level, it didn’t score high on our benchmark scale—only 6/10.

On this setting—7 minutes 25 seconds on the timer—the four pieces of bread on the upper tray were toasted to a nice golden brown color. However, the color became dark towards the edges, especially where the bread was less dense.

Additionally, a large portion of the bottom right piece of toast was significantly lighter, possibly indicating a cold spot in the cooking chamber. With such unevenness, we could only score the surface color a 6/10 despite the overall golden brown hue.

Moreover, due to the lengthy toasting time, the toast became very crispy but dry on the inside. Our head chef, Tuyet Pham, said this crispiness would be great for eggs benedict and especially soup, but maybe not omelets and sandwiches. Unfortunately, the dark edges produced a bitter taste, preventing it from getting higher than a 6/10 from our chef.

We toasted the second batch of four slices immediately after the first. We chose level 4 again whereupon the oven automatically calibrated the timer to 5 minutes 31 seconds.

Since the oven was already hot, the aforementioned cold spot became less apparent. The toast was not as crispy nor dry as the first batch, which made it more suitable for sandwiches and omelets.

However, the burnt edges were still a problem, so the oven received one final 6/10 for consecutive usability. If you want better results for the second batch, we recommend decreasing the toast level by one.

The Comfee wasn’t suitable for baking a 9-inch thick-crust meat pizza with a score of 5/10.

This oven took 11 minutes, which was over our time limit, to bake the pizza to a desirable outcome. Thus, it failed the cooking time section of our Pizza test.

The crust attained just a light golden color and was very soft, so it got a 6/10. There were some small bits stuck to the baking pan, but they weren’t hard to get rid of.

The toppings had uneven caramelization and were a bit dry throughout, so they scored a 6.5/10. The cheese was slightly melty, but some areas darkened a lot.

Our chef gave the pizza a 6/10 for taste.

For this pizza test, we didn’t choose the oven’s 400°F pizza preset because it didn’t match our Pizza test requirement of 450°F. Instead, we chose Turbo Convection as a suitable setting for baking pizza. Nonetheless, the results were not so favorable scoring only 6.4/10 on our testing scale.

We were, however, impressed that the oven only took 9 minutes to bake a 9-inch thick-crust meat pizza placed on the upper rack level. According to our accumulated data on average toaster oven performance, this deserved a 9/10.

Unfortunately, the oven lacks the high-intensity heating capability needed to crisp a crust effectively in such a short period of time, which the Toshiba AC25CEW-BS has. Consequently, parts of the crust bottom stuck to the grooves of the baking tray and the surface had a light golden color - so the score was only 5.5/10.

We had to stop baking because some of the meat and parts of the cheese started charring. It was a shame that the cheese didn’t completely melt before this, so we could only give the toppings a 6/10.

We were able to prevent the toppings from burning and the potential bitter taste. However, the crust and the topping weren’t good enough for the taste of the pizza to get a score higher than 5.5/10 from our chef.

The Comfee’s capacity barely fit a 3 lb chicken, which led to some problems during our Whole Roasted Chicken test. Overall, it left a few things to be desired and got a score of 7.1/10.

The oven took 1h 20m to cook the chicken, which was 20 minutes longer than the standard amount of time so it got a 6/10.

Even though we had to rotate the baking pan 3 times during roasting, most of the skin could only get a yellow color, similar to when it’s steamed. The only exception was the middle area, which was close to the upper heating elements and turned a golden brown color.

Nonetheless, the skin was soft so it could only get a 6.5/10. In addition, the skin on the back got stuck to the baking pan when we tried to flip the chicken.

The chicken was thoroughly cooked and the internal temperature was 183-189°F, which was only a little higher than recommended by the USDA, so we gave it a 9.1/10.

The meat was soft and juicy, so our chef gave it a 7/10 for taste.

The spacious interior of the Oster seemed a key factor in our Whole Roasted Chicken test, scoring an impressive 8.1/10. We placed a 3 lb chicken belly-up on the upper rack level and flipped it after the first 40 minutes.

After 1 hour and 10 minutes, the skin reached an acceptable roasted color scoring a 7/10 for cooking time. Our chef surmised that further roasting wouldn’t result in better skin caramelization. Thus, we stopped roasting to avoid overcooking the meat and inadvertently lowering the total score.

The skin had an appetizing golden color, except for the sides of the two drumsticks which were a little lighter in color. Compared to other benchmark tests, the skin only crisped slightly indicating the heating elements and convection system to be less than ideal/top-of-the-range. The results were good, enough for a 7.5/10.

In conclusion, the oven maintained an ideal temperature long enough to evenly cook an entire chicken throughout. We measured the internal temperature of the chicken and it was 181°F. This was very surprising and almost spot-on with the recommended 165°F - 180°F by the USDA—thus earning a whopping 9.8/10 for doneness.

Interestingly, the meat came out so tender that the bone simply fell off as we tried to carve the chicken. If the skin was crispier, the chicken would have received a higher than 8/10 for taste.

Baking 12 oz of french fries wasn’t a favorable task for the Comfee; it ended up with a 4.7/10.

Even after 35 minutes, the Comfee wasn’t able to produce a notable change in the texture and color of the fries. In addition, as the time limit for our Baked French Fries test was 25 minutes, this oven failed our cooking time criterion.

The fries lacked color, so they got a 6/10. The oven basically thawed the fries without really baking them resulting in soggy fries with a score of 5.5/10. Our chef could only give the fries a 6/10 for taste.

For our Baked French Fries test, the Oster was disappointing, scoring only 4.1/10. Our reasoning was the poor size ratio of the cooking chamber to the oven’s power output. The oven wasn’t able to maintain a high enough temperature for baking frozen fries, as opposed to the Ninja DT201.

After 30 minutes the fries showed no significant change in color—where the test time limit was 25 minutes! Therefore, we had no choice but to stop baking and give the fries a 0/10 for cooking time.

Most fries had a pale color as if they were air-dried instead of air-fried. Some small pieces had a light golden color, but that wasn’t enough to score higher than 5/10.

Texture-wise, the fries were soft but dry on the outside, barely enough for a 5.5/10. All things considered, the only silver lining was that the fries were cooked, so our chef gave them a 5/10 for taste.

The oven’s casing is painted white but also polished, so you won’t have to worry about it getting dirty easily. Besides the two back buffers that keep the oven from being pushed too close to the wall, the Comfee also features carrying handles on the sides.

What stands out to make an impression is the detachable crumb tray, similar to the Mueller MT-175. You can open it by tilting the unit slightly backward and pushing the dial on the tray towards the rear of the unit.

Our measurements of the oven’s footprint were 13.85" x 11.18" x 8" which only had marginal differences from the manufacturer's 14.6" x 11.4" x 8".

Considering the Oster’s large size, ventilation slats on all sides are a big plus. (+3). At first glance, the most stand-out feature was the tempered glass french door with cool-touch door handles (+3).

It has a rear buffer to maintain a cool distance from the wall, but we thought it could be greater(+2). Additionally, while the oven’s leg stoppers are sturdy, they are rather small.

Our measurements of the oven’s footprints were 21.53" x 19.96" x 12.79" which matched closely with the manufacturer’s 22" x 19.5" x 13". On a side note, we weighed the oven and it was 16.75 lbs while the manufacturer stated the entire package to be 13.87 lbs.

Cooking Functions Comfee CFO-BB101 Toaster Oven

Cooking Functions of the Oster XL Digital Convection Toaster Oven
The mode dial of the white Comfee CFO-BB101 Compact Toaster Oven has 3 cooking functions including Toast, Bake, and Broil.
  • Toast
  • Bake
  • Broil

If you know your way around the kitchen, the bake and broil functions will be all you need.

The eight cooking functions of the Oster TSSTTVFDDG Toaster Oven are in the center of the control panel. They include Toast, Bake, Broil, Turbo Convection, Pizza, Warm, Defrost, and Dehydrate. The oven’s right side has air ventilation holes.
  • Toast (level 1-6)
  • Bake (150°F-450°F)
  • Turbo Convection (150°F-450°F)
  • Broil (450°F)
  • Pizza (400°F)
  • Warm (150°F)
  • Defrost (150°F)
  • Dehydrate (150°F)

The Oster has eight cooking functions including Toast, Bake, Broil, Pizza, Warm, Defrost, Dehydrate, and Turbo Convection. Despite the name, Turbo Convection is basically Convection Bake—meaning this oven only has one convection level.

The standard Bake function and ‘Turbo’ Convection operate in the oven’s maximum temperature range, between 150°F to 450°F. The Toast function has 6 preset levels from Light to Dark, Meanwhile, the Pizza function is set to 400°F and Broil to 450°F—meaning neither can be adjusted.

The user manual recommends not to preheat the oven when using Defrost and Dehydrate. These two functions are set to 150°F—the lowest possible temperature —and cannot be adjusted. However, 150°F is a bit high compared to common dehydrators which operate at around 100°F.

For some reason, we couldn’t find the set temperature for Warm in the manual, but we measured the temperature to be 150°F.

Compared to the more common nichrome heating elements, the quartz heating elements produce more heat and cool down faster. They’re also easier to clean and more energy-efficient. However, they are not as durable and will suffer from permanent stains if grease splashes onto them while cooking.

Similar to most small toaster ovens, the oven doesn’t have internal lighting or a convection system and it only has two tray levels. In addition, while it’s common for units this size to have two heating elements, we usually found a less even heat distribution compared to units with four or more heating elements.

The cooking chamber of the Oster TSSTTVFDDG Toaster Oven has one nichrome heating element on top and two on the bottom, two rack levels, a shining light, and a fan cavity on the right wall.

The Oster uses three nichrome heating elements with an unusual looped design for the upper heating element (+3). Most similar large-capacity ovens we have examined have four upper heating elements, two bottom heating elements, and a combined power draw of 1800 W.

However, the Oster has only one upper heating element which bends across and around the cooking chamber’s ceiling to cover the same area as would four. Since the power draw is divided equally between working heating elements, we speculated this design choice was to accommodate the oven’s lower power draw of 1500 W.

The TSSTTVFDDG claims to have ‘easy clean interior walls’. While they are not grease-proof, our cleaning test showed that the oven was, indeed, easy to clean (+1).

The convection fan is situated on the right side of the cooking chamber (+2). While the oven has an interior light, it’s fully automatic with no manual operation (+2).

Having only two rack levels, the oven doesn’t really require guides on the glass door (-1). The manual recommends using the upper rack position for toast and pizza, and the lower one for other foods. It’s worth noting that the rack guide rails are assembled parts and not hollowed out of the cooking chamber’s walls like many other toaster ovens.

The baking rack should not be slid into the lower rack slot with the baking tray attached to the bottom. This will result in direct contact with the bottom heating elements.

Capacity

  • Width:

  • Height:
    6.9" (17.5 cm)

Although compact, the Comfee has enough capacity for 4 slices of toast, a 9-inch pizza, and barely enough for a 3 lb chicken. We measured the cooking chamber’s volume to be around 11 liters which was slightly different from the manufacturer’s provided 10 liters. However, it could just be a difference in measuring standards.

  • Height:

According to the manufacturer, the TSSTTVFDDG can take 14 slices of toast and two 16-inch pizzas on its two racks. However, our hands-on testing proved it fits only 12 slices (6 per rack, each requiring at least 4.5 x 4.5 inches of space)  or a 15-inch pizza. While it wasn’t clear what the maximum size for a whole chicken was, our tests indicated plenty of room for a 3 lb bird.

The manufacturer doesn’t state the interior capacity, but we measured the cooking chamber volume to be around 42.83 liters—our biggest number to date. However, we felt only two rack slots didn’t do justice to the oven’s capacity.

  • Rated Output:
    120 V ~ 60 Hz

The power cord is roughly 26.37"—enough length for household use. However, the back buffers aren’t designed to wrap the cord around, unlike many other toaster ovens.

  • Rated Output:
    120 V ~ 60 Hz

The power cord is 25.79" long which is enough for household use. However, it could be a bit longer since a toaster oven as large as the Oster requires at least 5 inches of clear space on all sides. The oven doesn’t have storage space for the cord like some ovens do.

The baking pan has ridges and grooves which can give your food attractive roasting marks and catch the dripping better. However, its coating isn’t completely non-stick, so it may be prone to some stubborn stains after a hefty roast.

The baking pan has ridges and grooves for creating attractive roast markings and catching drippings. It also has wide edges for a firm fit on the baking rack supports, unlike some other designs we’ve seen.

However, it’s not big enough to fit into the rack rail guides and can only go on top of a rack or attached beneath. This means it doesn’t make full use of the oven’s capacity. In addition, the tray is coated, but not completely non-stick so prone to stubborn stains.

Being a compact product, it’s understandable that the Comfee doesn’t have as many design features as bigger toaster ovens. Even though the price of this product is quite reasonable, it doesn’t have a very sturdy build. In addition, the door can open if you tilt the oven.

The TSSTTVFDDG is light for its size and has a graspable rectangular shape making it easy to carry or position on a counter (+2). It also has a sturdy build and durable stainless steel casing (+4). The LCD is black while the numbers are yellow and the settings are red, making everything easy to see (+1).

Unfortunately,  we found that the flat buttons often required some force to register (-1). Moreover, the door hinge could be firmer thus preventing the door from slamming shut.

Even though the Comfee has only two simple control knobs for time and temperature, there are a few things to keep in mind. For the timer knob, when setting it to less than 5 minutes, always rotate past 5 minutes (Med) and then rotate back to the desired time.

For the temperature knob, both the heating elements function when the oven is set from 150°F to 450°F. On Bake, only the bottom element functions, and the oven’s internal temperature is maintained at approximately 400°F-425°F. On Broil, only the top element functions, and the temperature stays steady at approximately 425°F-450°F.

The other problem relates to time and temperature, both of which cannot be adjusted precisely. Nonetheless, you can get used to adjusting time and temperature on this oven after a few times. You can also use an oven thermometer and an external timer to help with this.

The Oster’s controls are easy to understand since what you see is what you get (+2). Therefore, the LCD doesn’t provide any extra information but it’s easy to read (+2).

The buttons have only a single function and are easy to tell apart(+2). Although the manual says you can press the Stop/Cancel button twice to turn off the oven, we weren’t able to do so (-1).

The temperature can be adjusted in increments of 5°F and the timer runs from one minute to six hours, which is quite impressive (+1). Time can be adjusted in increments of 1 minute up to  2 hours and in increments of 0.5 hours above 2 hours (+1).

To set up the clock, press the clock button once and the clock will flash. Then, use the arrow keys to set the hour and press the clock button again to likewise set the minutes. Finally, push the clock button or the start button to set the time (+1).

Ease of Use

Oster French Door Toaster Oven Ease of Use

With two control knobs, it’s very simple to adjust time and temperature during cooking. When the timer runs out, a bell will sound and the oven will shut off.  The oven does not have a digital display, so you can freely leave it plugged in and not worry about power consumption.

It’s easy to keep the door partially open to let food cool down, but keep in mind that this doesn’t stop the cooking. Also, be careful as the oven’s exterior gets hot to the touch quite quickly.

As you select a function, the corresponding icons will illuminate in the LCD screen. The TSSTTVFDDG has an automatic preheat phase which is only applicable for the Bake and Turbo Convection Bake functions (+1).

After setting the time and temperature, you then push start and the display will show PrE indicating the oven is in the preheating phase. You can bypass this phase by pressing the start button a second time.

Preheating takes roughly 5 minutes to around 300°F regardless of the  temperature you set. You can readjust the time and temperature only after the preheating phase.

Interestingly, we found that the oven would return to preheat mode after adjusting the temperature until the new input temperature was reached and not just 300°F. This is also stated in the user manual.

The racks fit perfectly into the rail guides thus preventing accidents when placing food in the oven (+3). When the cooking cycle begins, the interior light will turn on automatically and then off when the cooking cycle ends (+2).

The french door and its cool-touch handle allow you to stay away from the heat wave when opening after cooking (+4). The doors are also single-pull which is very convenient. However, the doors cannot open partially and can slam shut if your hand slips (-2).

Unlike some ovens, opening the door doesn’t stop the oven or the interior light (-2). The oven casing can get very hot after long cooking times at high temperatures, so you should take care (-1).

When the cooking cycle finishes, the oven will beep once, switch off the heat, and return to the clock screen. It’s advised to unplug the oven after use.

We cleaned the Comfee following our toaster oven cleaning guide without much problem. Thanks to the detachable crumb tray, not only were we able to remove the crumbs, we also had better access to clean the oven’s interior.

However, some of the crumbs got stuck inside the bottom heating element’s guard. As for the baking pan, without a good coating, it got a slight discoloration after our Whole Roasted Chicken test.

The stainless steel exterior of the Oster was very easy to clean (+2). Even though the interior doesn’t have a non-stick coating, there are no tricky nooks and crannies, so cleaning didn’t require much labor (+4).

After roasting a chicken, the baking pan accumulated some stubborn stains which we were able to remove even with a baking soda paste and water (+1.5). We were worried the grease could splash inside the fan cavity while cooking, but this was not the case.
