Comparing the Comfee Toaster Oven (CFO-BB101) to the Breville Smart Oven Pro (BOV845BSS), above all else, showcases the weaknesses that a small and a large unit can have. Of course, nothing changes the fact that the Breville is simply better in every way.

The Comfee has a neat detachable crumb tray that makes cleaning its small cooking chamber easier than its peers. However, it lacks the digital control panel, convection system, lighting, and has fewer heating elements than the Breville has. Moreover, the Breville has more accessories and a thicker casing for better heat insulation.

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.

On the other hand, the Breville had good scores across all the tests. However, they aren’t as high as other units with the same power output. We suspected there may be inconsistency in its quartz heating elements.

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 by choosing toast level 4—the middle one out of the 7 options—for 4 pieces which we placed on tray level 2. The four pieces of bread came out only slightly toasted on top. We then chose level 5 and the surface color was more appetizing but less even.

So, we tried again one last time at level 6 but it produced four completely brown pieces of toast which were also a bit dry. In the end, we settled for level 5—5 minutes 13 seconds on the timer—as the best possible option with a score of 6.8/10.

At this level, the toast had a perfect golden brown color around the center of the oven. However, it was lighter the further it got to the rear, so we could only give it a 7/10 for even surface color.

The unevenness also translated to the texture where the toast achieved great crispiness in the golden brown areas but got softer in the lighter areas. This resulted in a 6.5/10 for taste from our chef.

Our head chef, Tuyet Pham, determined they would be good to have with omelets and sandwiches. They could be served with soups or eggs benedict but wouldn't make a perfect pairing.

We placed the second batch of four in immediately after the first one. We chose level 5 again whereupon the oven automatically deducted the timer to 3 minutes 42 seconds.

Because the oven was already hot, the second batch showed an increase in evenness for both surface color and crispiness deserving a 7/10. This batch would be more suitable for soups.

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 our Pizza test, we didn’t use the pizza presets because they didn’t include the correct size for our choice of pizza. This was also a good chance to test out the Breville pizza pan, but we were surprised to find the overall score ended up at 6.8/10.

Thanks to the oven’s strong power output and convection setting, it only took 4 minutes to bake a 9-inch thick-crust meat pizza placed on tray level 2. This was extremely fast and deserved a 10/10 according to our data on average toaster oven performance.

However, the pizza still had a problem with cooking evenness. A quarter of the entire crust was golden brown but the rest of it lacked color. As you can imagine, the golden brown part was crispy on the outside and soft on the inside while the lighter part was simply soft throughout. Thus, we could only give the crust a 6/10.

The same issue applied to the toppings which had a nice caramelization where the crust was golden but not much in the substandard area. The cheese was also not quite melty so the toppings also got a 6/10.

Altogether, our chef gave the pizza another 6/10 after tasting it. We chose not to increase the cooking time of the pizza as it could result in burning the part of the crust and toppings that were already properly baked.

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.

For our Whole Roasted Chicken test, we placed a 3 lb chicken in a belly-up position onto the broiling rack and baking pan combo on tray level 1. The outcome was pretty satisfactory, scoring a 7.5/10.

The Breville took 1 hour to roast the chicken to a desirable color which was our standard for an 8/10. The skin overall had a golden color, especially at the wings and the tips. However, it still had some very light areas.

In addition, when we flipped the chicken after the first 40 minutes, some of the skin on the back of the chicken got stuck to the broiling rack. This was an indication that the skin was soft and didn’t crisp up much despite having the convection fan deployed. Thus, we gave the skin a 7/10.

The oven was able to maintain a good internal temperature so the chicken was cooked all the way through leaving behind no pink spots. However, the cooking time was a little long, so the chicken’s internal temperature ended up at 198°F which was higher than the recommended 180°F by the USDA. We gave the doneness of this chicken an 8.6/10.

Nonetheless, the meat wasn’t dry and combined with the skin it was enough to get a 7/10 for taste from our chef.

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.

Despite the power draw of 1800 W, the Breville didn’t perform as well in baking french fries as many toaster ovens with the same output earning a 6.1/10. Looking at the results from the Ninja DT201, our assumption was that the broiling rack wasn’t as efficient for this purpose as an air fryer basket.

For our Baked French Fries test, we didn’t turn on the Frozen Foods toggle because we needed to keep track of the exact cooking time. The oven took 24 minutes to bake 12 oz of frozen fries on tray level 2 which wasn’t very fast. Compared to many other toaster ovens we’ve tested, it could only get a 6/10 for cooking time.

Even though we gave the fries a toss after the first 10 minutes, they still came out with uneven coloring scoring a 6.5/10. Most of the thinner fries had a pretty good golden color while most of the thicker ones had a much lighter color.

To the same degree, the fries had different textures throughout earning it a 6/10 for this testing component. The pieces with a golden color were crispy outside and soft inside while the lighter ones were mostly just soft all the way through.

With all of that in mind, our chef couldn’t give a score higher than 6/10 after tasting the fries.

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".

An exterior feature that stood out to us on the Breville is its side-positioned carrying handles which double up as air ventilation holes for the convection system. We were also impressed by the indicators on the glass door that direct you to its three tray levels and many cooking functions.

The Breville has an interesting automatic eject feature for when the oven rack is in the middle guide rail. This is achieved thanks to a magnet in the corresponding position on the oven door.

Further attention to the design shows in the convenient slide-out crumb tray and strong base stands. The oven’s door handle is cool-touch and provides a good grip. Unfortunately, the back buffers are not long enough to create ample space between the back of the oven and the wall.

Our measurements of 18.39" x 15.94" x 10.78" for the oven pretty much coincided with the dimensions provided by the manufacturer—18.5" x 14.5" x 11". The 1.5-inch difference in width is probably because we took the door handle into account.

The Breville has 3 control knobs for function, temperature, and timer. Its five buttons include four toggles for temperature conversion, interior light, convection fan, and Defrost feature. The Start/Cancel button and the digital display both shine red when the oven’s cooking.

The LCD screen will display ‘E01’, ‘E02’, or ‘E05’ when there is a non-resettable issue with the appliance. When this happens, immediately unplug the cord from the wall outlet and call the Breville Customer Service Center.

The ‘E03’ shows up when the oven temperature exceeds its design limit. Should this occur, unplug your oven, allow it to cool for 15 minutes, then plug it back in.

The ‘E04’ appears when the room temperature is below the set minimum. If this happens, unplug the oven and move it to a warmer area.

Cooking Functions Comfee CFO-BB101 Toaster Oven

Cooking Functions of the Breville BOV845BSS Smart Oven Pro
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.

Breville BOV845BSSUSC has 10 cooking functions: Toast, Bagel, Bake, Roast, Broil, Pizza, Cookies, Reheat, Warm, Slow Cook.
  • Toast (level 1-7)
  • Bagel (level 1-7)
  • Bake (1 minute - 10 hours)
  • Roast (1 minute - 2 hours)
  • Broil (300°F, 400°F, 500°F; 1 minute - 20 minutes)
  • Pizza (6″-13″; Fresh/Frozen)
  • Cookies (1 minute - 1 hour)
  • Reheat (1 minute - 2 hours)
  • Warm (1 minute - 2 hours)
  • Slow Cook (2 hours - 10 hours)

The Breville has 10 cooking functions which make full use of its wide timer and temperature ranges. Functions that allow for the full adjustment of temperature (120°F - 450°F) include Bake, Roast, Cookies, Reheat, and Warm.

The Toast and Bagel functions have 1-7 levels which include predetermined timers for 1-6 slices. This toaster oven went the extra mile as most others don’t take the number of slices into account.

Meanwhile, the pizza function includes presets for sizes ranging from 6" to 13" along with fresh or frozen pizzas. The Broil function has three preset temperatures including 500°F, 400°F, and 300°F for up to 20 minutes.

The Slow Cook function has two settings: ‘LO’ with a timer of 4-10 hours and ‘HI’ with 2-8 hours; and you can further adjust the timer up and down while cooking. After the Slow Cook cycle finishes, this function automatically turns to Keep Warm at 175°F for up to another 2 hours.

The CFO-BB101 uses 2 quartz heating elements which use infrared light to cook. Each one has its own safety guard to prevent direct contact with baking pans and trays.

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 BOV845BSS has a non-stick interior coating which explains the black color. The black interior isn’t a problem though thanks to the oven’s interior light. When necessary, you can remove the glass cover to change the interior light bulb which is a G9 type, 25 W, 120 V.

Each of the three tray levels has a safety hook to prevent the oven rack from accidently sliding all the way out. However, only the bottom one is positioned further in, specifically for this purpose. The convection system, while quite powerful, is pleasantly quiet.

The Breville has five quartz heating elements that use infrared light to cook. Compared to the more common nichrome heating elements, these heat up and cool down faster while also being easier to clean and more energy-efficient but don’t last as long in terms of durability.

For this unit, each heating element has a safety guard to prevent direct contact with baking pans and trays. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.

  • 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:
    8.3" (21.0 cm)

The Breville’s cooking chamber has a capacity of 25 liters which is quite common among large toaster ovens. This was one of the rare occasions where the cooking chamber’s volume that we measured matched the manufacturer’s stated capacity.

Many large units can also fit 6 slices of toast but not all can fit a 13-inch pizza like the Breville. This oven can also fit a 9-cup muffin tray or a 4.16-liter Dutch oven.

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 Breville has a sturdy build and is made from durable stainless steel. The oven has good heat insulation and a good convection system so the casing rarely gets hot to the touch—only after a long cooking time at a high temperature (>400°F).

Its LCD has a good color contrast, the control dials turn smoothly, and the buttons have good responsiveness. On another note, this unit doesn’t provide enough oven racks to make full use of the three tray levels and additional accessories.

Note: This product adheres to the California Proposition 65.

User Control

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 timer of the Breville is specified by the minute. The temperature can be adjusted in 5°F/5°C increments by turning the knob slowly and in 10°F/10°C increments by turning the knob fast.

You can freely adjust the time and temperature while the oven is running but will need to press Cancel to change the cooking function. Keep in mind that this may repeat the automatic preheat phase if the temperature is lower than the manufacturer’s set point.

Regarding the extra unique features, the Temperature Conversion button is a nice touch for international users. The convection setting can be applied to almost all cooking functions except for Toast, Bagel, and Broil.

The Frozen Foods button adds a predetermined amount of time but only to the Toast, Bagel, Pizza, and Cookies functions. However, we didn’t find it very helpful since cooking time depends heavily on the food quantity and personal preference.

As for the extra cooking functions, the Pizza presets, with predetermined timers, aren’t very useful as they allow for temperature adjustment but don’t take the current temperature into account. The same goes for the Slow Cook function which has a predetermined temperature that isn’t stated in the manual.

According to our observation, the oven reaches and maintains at 325°F on both Low and High so we didn’t get the point of having two settings. In addition, these temperatures are quite high compared to more common slow cookers’ which are around 200°F on low and 300°F on high.

If you want to adjust the temperature for slow cooking in this oven, you can choose the Bake function for which the timer also reaches ten hours.

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.

The Breville has an automatic preheat phase for functions that allow for temperature adjustment as mentioned above. According to the manufacturer, this feature will preheat the oven to 75% of the input temperature before sounding an alert. However, our observation showed that it would always preheat to around 300°F taking about 4m 55s regardless of the input temperature.

Due to the eject feature mentioned above, keep in mind to open the door slowly to prevent the rack from sliding too far outward. The door can be kept partially open at an 80° angle to let food cool inside the oven. Doing this doesn’t stop the oven, unlike some others. Be careful as the door can slam shut if you slip while closing.

When the automatic preheat phase or the cooking cycle ends, the interior light will turn on and then turn off after 30 seconds, similar to when you press the light switch. Unfortunately, there’s no way to keep the light on indefinitely.

If not used for 10 minutes, the oven goes into standby mode until you press Start again. Nonetheless, it’s still advised to unplug the oven after use. Your customized setting will remain in the memory of the oven until changed or the oven is unplugged from the power outlet.

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.

Cleaning the Breville was extremely easy thanks to its stainless steel exterior and non-stick interior. There were some tricky nooks and crannies in the cooking chamber but luckily, there was minimal grease splashing after all of our tests.

The enamel baking pan and broiling rack sported some stubborn stains from the roasted chicken even after we washed them with dish soap. Nonetheless, we took care of them quite easily by brushing them with a paste of baking soda and water. 

The slide-out crumb tray was also helpful for cleaning up the crumbs but we still had to tilt the oven to get all of the crumbs out.
