When tested with equal amounts of food, the COMFEE CFO-BB101 suffered defeat at the hands of the Black+Decker CTO6335S in all of our performance tests. We’d recommend you decrease the portion sizes from our test amounts.

It was understandable for a smaller toaster oven to cook less food at a time than a large one. However, there were other factors that may have contributed to their difference in performance.

The Comfee consumes minimal energy with its two quartz heating elements drawing 1000 watts. However, that energy savings unfortunately meant it couldn’t maintain a high temperature, resulting in low scores in baking toast, pizza, and fries.

The Black+Decker was nowhere near perfect either, especially in baking french fries. Despite having a higher power rating of 1500 W, the oven still wasn’t able to heat its four quartz heating elements fast enough to keep up with its capacity. It does have a strong advantage in the form of a convection system, though.

The Black+Decker’s buttons and the Comfee’s dials are both simple to use in their own way. However, the former’s various functions are extra helpful to beginners. It’s also equipped with a broiling rack in addition to the basic oven rack and baking pan.

Overall, the COMFEE CFO-BB101 is not a bad choice if you want to save energy and space on the kitchen counter. On the other hand, the Black+Decker CTO6335S takes up more space but operates longer in your kitchen with its durable stainless steel outer shell.

50% * 5.5 = 2.8
Even Surface Color: 6
20% * 6 = 1.2
Consecutive Usability: 2
30% * 2 = 0.6
  • Function: Toast
  • Number Of Slices: 4
  • Toast Level: Medium
  • Cooking Time: 3m 50s
  • Second Batch: 3m 50s
  • Convection: No

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.

Taste: 7.5
50% * 7.5 = 3.8
Even Surface Color: 7

  • Function: Toast
  • Number Of Slices: 4
  • Toast Level: 4/7
  • Cooking Time: 5m 10s
  • Second Batch: 3m
  • Convection: No

With our Toast test, we were able to determine that level 4—5 minutes 10 seconds on the timer—was the best option scoring a 7/10. Levels 3 and 5 respectively had a lighter and darker than ideal, although even, surface color.

The toast level 4 of the Black+Decker scored a 7/10 for color. The four pieces had areas of different colors ranging from golden brown to just slightly golden. This was probably due to uneven heating of the elements and the convection fan not running.

Despite the color, the first batch was crispy on the outside and soft on the inside so we gave it a 7.5/10 for taste. Our head chef Tuyet Pham determined that it would go great with eggs benedict and omelet.

Even with the automatic toast time adjustment feature, the quality of the second batch was reduced in every aspect. The color was lighter and the texture was less crispy so we had to give it a 6/10 for consecutive usability. If you want the second batch to be the same as the first, lower the toast level by one.

  • Convection: No

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.

Cooking Time: 7.5

  • Function: Bake
  • Temperature: 450°F
  • Cooking Time: 7m 30s
  • Convection: Yes

The Black+Decker did an ok job of baking a 9-inch thick-crust meat pizza earning it a 6.8/10.

Compared to the recommended 10 minutes on the label, it took 7m 30s to bake the pizza, which was fairly solid. However, after comparing it to other toaster ovens in our Pizza test, we could only give it a 7.5/10.

The crust had a good golden brown color but was soft and a little dry — possibly due to the longer cooking time. Thus, it could only get a 7/10.

The toppings were mostly dry with an uneven coloring, plus the cheese wasn’t melty so it got a 6.5/10.

In the end, our chef gave the pizza a 6.5/10 for taste.

  • Function: Bake
  • Temperature: 350°F
  • Cooking Time: 1h 20m
  • Convection: No

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.

Cooking Time: 8

40% * 7.5 = 3.0
  • Function: Bake
  • Temperature: 350°F
  • Cooking Time: 1h
  • Convection: Yes

Following our Whole Roasted Chicken test guidelines, we placed a 3 lb chicken on a broiling rack on a baking pan of the Black+Decker with plenty of space to spare. The abundance of space gave it some advantages over smaller units like the Breville BOV450XL despite a lower power output. Overall, the Black+Decker received a 7.7/10 for this test.

It took the oven 1 hour, the standard amount of time, to roast the chicken to a desirable color so we gave it an 8/10. The skin came out a light golden color but it was uneven despite being flipped after the first 40 minutes. In addition, it was soft, so it got a 6.5/10.

The chicken was thoroughly cooked but the internal temperature was a tad bit high at 189°F-192°F compared to the USDA recommended 165°F-180°F so we gave it an 8.8/10. The meat was very juicy but the lack of roasted aroma and crispy skin resulted in a 7.5/10 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.

Cooking Time: 0

  • Function: Bake
  • Temperature: 400°F.
  • Cooking Time: 25m 50s
  • Convection: Yes

With a score of 5.6/10, the Black+Decker left a lot to be desired in the Baked French Fries test. In comparison, the same-sized Cosori CO130-AO did a much better job with its higher power output and air fry basket.

This oven took 25m 50s to bake 12 oz of fries which was just a bit too long over the limit of our Baked French Fries test. Thus, it failed our cooking time section. Coloring was uneven among the fries ranging from nicely golden to almost none so they could only get a 7/10.

The textures were also uneven and, worse, none was particularly good. The golden fries were only a little crispy and the ones that lacked color were soft. Overall, it was a 6.8/10 for this test.

Our chef gave the resulting fries a 7/10 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".

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 Black+Decker only has two tray levels but you can make use of the flippable rack to effectively create two more levels. The oven has a convection system but no internal lighting—unlike the Ninja DT201—which can be an inconvenience considering the interior is black.

The oven has quartz heating elements that use infrared light to cook. They have their own safety guards to prevent direct contact with baking pans and trays.

Compared to the more common nichrome heating elements, they produce more heat and cool down faster. They are also more energy-efficient and easier to clean but don’t last as long in terms of durability. 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.

The baking pan is large and, being 100% compatible with the broiling rack, it catches all the drippings. This prevents any hot mess from dirtying the heating elements thus mitigating that potential fire hazard. However, it’s not 100% non-stick so you may have some stubborn stains to deal with after a heavy roasting session.

Build Quality

7.0

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 Black+Decker CTO6335S is equipped with a tamper-resistant screw to prevent removal of the outer cover. However, the bottom tray can easily slide out and the door can also open if you tilt the oven.

Throughout our tests, we noticed that the oven’s large capacity is somewhat counteracted by its power output of 1500 W. We speculated on its ability to perform more efficiently if it were 1800 W.

User Control

8.0

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 Black+Decker has 8 functions but the convection toggle is only applicable to Bake. There’s an indicator light for when a function starts and stops — which are two separate buttons on the control panel.

For all functions except Toast and Bagel, you can push the increment and decrement buttons once to change the temperature in increments of 5°F and hold to change in increments of 25°F. After pressing the Timer button, the same goes for cooking time but in increments of 1 minute and 10 minutes. For Toast and Bagel, simply choose a level from 1 to 7.

Unfortunately, even though the label shows a stay-on function, we couldn’t find it in the control panel or the user manual. A small thing we didn’t like about the buttons was that they sometimes didn’t respond well.

4.0

Ease of Use

5.0

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.

For all functions except for Toast and Bagel, the Black+Decker has an automatic preheat feature. This will always heat the heating elements to 350°F, which takes around 4m 20s, before starting the actual timer. Then, the internal temperature will gradually stabilize around your input temperature.

One thing to note is that you cannot change the temperature or time during the automatic preheat cycle. You can only do so once the oven reaches the selected temperature.

Keep in mind that the oven’s exterior gets hot to the touch quite quickly. In addition, it doesn’t turn off upon opening the door, unlike some others. The door also can’t be opened partially.

This oven beeps with each push of a button and does so three times when it finishes cooking. The oven always remembers the last selected setting until it’s unplugged. It’s advised to unplug the oven after you finish using it as the digital display doesn’t turn off after a period of no interaction.

Cleanability

6.0

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.

We cleaned the Black+Decker following our toaster oven cleaning guide. With the oven having an internal and external coating, cleaning was quite straightforward.

However, even with the slide-out crumb tray, we still had to tilt the oven to get all of the crumbs out. In addition, some of them got stuck inside the heating element safeguards and we had no way of getting them out.
