Comfee Toaster Oven (CFO-BB101) vs Cosori Air Fryer Toaster Oven Side-by-Side Comparison




Our Verdict
- Performance (50%)5.3/10
- Design (25%)2.9/10
- Usability (25%)4.5/10
- Performance (50%)8.0/10
- Design (25%)9.4/10
- Usability (25%)8.3/10
The Comfee Toaster Oven (CFO-BB101) is small while the Cosori Air Fryer Toaster Oven (CO130-AO) is large. Their battle already ended before it began as the Cosori is our definitive best-to-buy pick while the Comfee just isn’t very good.
The Comfee has a neat detachable crumb tray that makes cleaning its small cooking chamber easier than its peers. However, it lacks the intricate control panel with an informative digital display and intuitive buttons that the Cosori has. Moreover, the Cosori 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 Cosori delivers much more consistent and outstanding cooking results compared to the Hamilton thanks to its high power output and convection settings.

Toast




- 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.




- Function: Toast
- Number Of Slices: 4
- Toast Level: 2/7
- Cooking Time: 5m 49s
- Second Batch: 3m 50s
- Convection: No
We started our Toast test with four pieces of white bread. We ran the toast function at level 3. The results were good, but the color was a bit too brown to be ideal. After examining the outcome on level 2, it was clear that was the best option, earning a score of 7.6/10 in total. We also tried toasting at level 1, which resulted in lightly toasted bread, for reference.
At level 2, which automatically set the timer for 5 minutes 49 seconds, the four pieces of toast mostly had a beautiful golden brown color. However, the existence of lighter areas, especially on the bottom side, kept it from being perfect. We considered it worthy of an 8/10 for even surface color.
The taste deserved another 8/10 thanks to the toast’s crispy surface and soft, moist interior. Our head chef, Tuyet Pham, determined the toast would complement pretty much anything, including sandwiches, omelets, eggs benedict, and soup.
After the first batch of toast, we immediately placed the second batch in the oven. The toast level 2 program automatically reduced the time to 3 minutes 50 seconds to account for the last batch’s residual heat.
However, this seemed like too much of a reduction, since the toast came out mostly lacking in color. It wasn’t very crispy either, so we could only give the oven a 6.8/10 for consecutive usability.
Pizza




- Function: Bake
- Temperature: 450°F
- Cooking Time: 11m
- 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.




- Function: Bake
- Temperature: 450°F
- Cooking Time: 3m 30s
- Convection: Yes
The Cosori’s ability to maintain a high temperature really shined in our Pizza test, garnering a score of 7.6/10.
With a high power output and powerful convection system, it only took 3 minutes 30 seconds to bake a 9-inch thick-crust meat pizza placed on tray level 2. This was extremely fast and deserving of a 10/10, the same as the Cuisinart TOA-60 which has the current highest pizza score.
However, the short cooking time resulted in uneven heating in the pizza crust and toppings.
While the bottom right quarter of the crust was golden brown, the rest didn’t have much color. Only that well-cooked part was crispy while the rest was soft, so we gave the crust a 7/10.
The same happened to the toppings. The bottom right quarter had a lot of caramelization—to the point that the onions even charred—while the rest was only mildly caramelized. In addition, the cheese wasn’t very melty, so we gave the toppings a 7/10 as well.
Taste-wise, our chef said it would be better if it weren’t for the slight bitterness from the charred onions. She gave the pizza another 7/10.
Whole Roasted Chicken





- 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.






- Function: Rotisserie
- Temperature: 350°F
- Cooking Time: 40m
- Convection: Yes
We’ve conducted our Whole Roasted Chicken test a great many times, and the Cosori wasn’t the only one with a high power output and powerful convection system. What set it apart was its rotisserie kit and function.
In addition, the large cooking chamber had more than enough space for a 3 lb chicken to rotate smoothly with a baking pan below to catch the drippings, unlike the Instant Omni Plus 18L. Everything together scored a whopping 8.9/10.
The oven took only 40 minutes to roast the chicken to a beautiful color. That was the fastest time we’ve had so far, earning it a perfect 10/10. The skin was mostly golden with some appetizing golden-brown color at the wings and the tips.
However, it seemed like the skin cooked a bit too quickly and the fat wasn’t fully rendered, so the skin wasn’t very crispy. Nonetheless, the skin still deserved an 8.5/10.
What impressed us most was the near-perfect doneness—9.9/10—in such a short amount of time. The chicken had no pink spots and a consistent internal temperature of 178°F-181°F. It was basically spot-on to the USDA’s 165°F-180°F recommendation.
Unfortunately, for some reason, the meat wasn’t as juicy as we had expected. Combined with the less-than-crispy skin, our chef couldn’t give the chicken a higher score than 8/10 after tasting it.
Baked French Fries




- Function: Bake
- Temperature: 400°F.
- Cooking Time: 35 m
- Convection: No
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.




- Function: Bake
- Temperature: 400°F
- Cooking Time: 17m
- Convection: Yes
The Cosori took on our Baked French Fries test with its air fryer basket and scored an 8.1/10.
It took 17 minutes to bake 12 oz of frozen fries on tray level 2—quite fast compared to most. After comparing it with other units from our data, we gave it an 8.4/10 for cooking time.
The fries mostly had a great golden color with some of the thinner pieces looking the most appetizing. However, some thicker pieces weren’t as golden, so we gave the fries an 8/10 for color.
The same can be said about the texture of the fries, which earned another 8/10. Most of the fries were crispy on the outside and moist on the inside, but the thinner ones were a bit dry and the thicker ones weren’t crispy enough.
Overall, though imperfect, the fries were delicious enough to get one final 8/10 taste score from our chef.

Exterior






- Weight:5.4 lbs (2.4 kg)
- Length:13.8" (35.2 cm)
- Width:11.2" (28.4 cm)
- Height:8.0" (20.3 cm)
- Material:Stainless steel
- Color:White
- Door Handle:cool-touch
- Tray Indicators:No
- Crumb Tray:Detachable
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".






- Weight:15.7 lbs (7.1 kg)
- Length:20.0" (50.7 cm)
- Width:17.3" (44.0 cm)
- Height:12.6" (32.0 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:Cool-touch
- Tray Indicators:No
- Crumb Tray:Removable
During our assessment, a prominent aspect of the Cosori toaster oven is the air ventilation holes on all sides of the casing to accommodate its powerful convection system. In addition, the glass door has indicators corresponding to the oven’s three tray levels and twelve cooking functions.
The oven doesn’t have carrying handles but it’s not heavy for its size so it’s not a big problem. Our measurements of 19.96" x 17.32" x 12.6" pretty much aligned with the manufacturer’s 20.1" x 16.5" x 12.5" with marginal differences being less than one inch. The difference in width is probably because we took the door handle into account.

The LED screen will display ‘E1’ when there’s an open circuit in the temperature monitor and ‘E2’ for a short circuit.
Cooking Functions Comfee CFO-BB101 Toaster Oven

- Toast
- Bake
- Broil
If you know your way around the kitchen, the bake and broil functions will be all you need.
- Toast (level 1-7)
- Bagel (level 1-7)
- Pizza (150°F - 450°F, 1 minute - 6 hours)
- Bake (150°F - 450°F, 1 minute - 6 hours)
- Roast (150°F - 400°F, 1 minute - 6 hours)
- Air Fry (150°F - 400°F, 1 minute - 6 hours)
- Broil (150°F - 450°F, 1 minute - 6 hours)
- Cookies (150°F - 450°F, 1 minute - 6 hours)
- Rotisserie (150°F - 400°F, 1 minute - 6 hours)
- Dehydrate (100°F - 180°F, 30 minutes - 24 hours)
- Ferment (80°F - 110°F, 30 minutes - 12 hours)
- Warm (140°F - 230°F, 1 minute - 12 hours)
Besides the basic cooking functions, which already have a wide time and temperature range, the Cosori air fryer toaster oven also has various practical additional cooking functions allowing for even wider time and temperature ranges.
The ones that impressed us the most were Warm, Dehydrate, and Ferment which can maintain the oven at as low as 140°F, 100°F, and 80°F respectively. Looking at a number of recipes, these temperatures fit their intended purpose, which means this oven can act as a family-sized dehydrator and dough proofer.
Note that only the bottom heating elements operate during these functions.
Interior



- Heating Elements:2 quartz
- Convection Fan:No
- Lighting:No
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
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.




- Heating Elements:4 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:3
- Rotisserie:Yes
- Safety Hook:No
The interior features include a convection fan, light, a rotisserie socket and bracket, three tray levels, and four nichrome heating elements. To be nitpicky, we think it’s a shame it doesn’t have a non-stick coating, so it may accumulate some stubborn stains.
Capacity

- Length:10.2" (25.8 cm)
- Width:9.6" (24.5 cm)
- 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.

- Length:14.2" (36.0 cm)
- Width:13.8" (35.0 cm)
- Height:9.8" (25.0 cm)
The Cosori has a spacious cooking chamber even compared to other large ovens. It can accommodate 6 slices of toast, a 13-inch pizza, or a 5-pound chicken.
We measured the volume to be around 31.49 liters compared to the manufacturer’s listing of 30 liters. The difference is minor and could just be a difference in measuring standards.
Power Cord of the Comfee Small Toaster Oven

- Length:26.4" (67.0 cm)
- Type:2-prong plug
- Power:1000 W
- 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.

- Length:40.9" (104.0 cm)
- Type:3-prong plug
- Power:1800 W
- Rated Output:120 V ~ 60 Hz
The power cord has plenty of length for household use—roughly 40.94 inches. It protrudes from the bottom of the oven, unfortunately, so it may create awkward kinks now and then.
Accessories

- Length:10.2" (25.8 cm)
- Width:8.3" (21.0 cm)
- Height:0.4" (1.1 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The rack fits perfectly with the guide, which helps prevent accidents when placing your food in the oven.

- Length:14.2" (36.0 cm)
- Width:13.4" (34.0 cm)
- Height:0.3" (0.7 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack fits perfectly onto its guide rails to prevent accidents when placing food in the oven. It’s also shaped to maximize the space inside the cooking chamber.
Accessories

- Length:10.2" (25.8 cm)
- Width:7.9" (20.0 cm)
- Height:0.7" (1.7 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
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.

- Length:14.2" (36.0 cm)
- Width:11.8" (30.0 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan also fits the guide rails to fully utilize the cooking space. It has ridges and grooves which can give your food attractive roasting marks and allow drippings some space to flow away. Its coating isn’t completely non-stick, so it may gather some stubborn stains, though.
Build Quality

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 Cosori is made from high-quality and durable 304 stainless steel. The thick casing provides good insulation in addition to a well-thought-out convection system. Thus, the oven only gets hot to the touch after a long cooking time at a high temperature (>400°F).
As for the control panel, the LED display is very easy to see, the control dials turn smoothly, and the buttons are responsive. The accessories are designed to make the most out of the cooking chamber’s interior space.
Comfee CFO-BB101 Small Toaster Oven Usability

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 convection feature can toggle between normal and high, and neither setting makes much noise. The fan can run on all functions except Toast and Bagel.
Since time and temperature are controlled by a single dial, you must toggle between functions. Press the dial’s face to switch between them. Temperature can be adjusted in increments of 5°F or 2°C-3°C.
The timer, however, has different steps depending on the cooking function. For Pizza, Bake, Roast, Air Fry, Broil, Cookies, Rotisserie, and Warm functions, the timer can be adjusted in increments of 1 minute until it reaches 60 minutes, then in increments of 5 minutes from 1-2 hours, in increments of 10 minutes from 2-3 hours, and in increments of 15 minutes from 2-3 hours. For Dehydrate and Ferment functions, the timer only adjusts in increments of 30 minutes.
On top of the many practical cooking functions, the ease with which you can adjust time and temperature makes this oven, overall, simpler to use than many other digital ones. In addition, you can press and hold the time and temperature dial to turn off the display to save energy while you’re not cooking.
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 Cosori has an automatic preheat phase which engages for the Pizza, Bake, Roast, Broil, Cookies, and Air Fryer functions. If the oven’s already hot, the function will recognize that fact and reduce its preheating time.
This toaster oven is one of the rare units that actually preheat to the input temperature. Most others simply heat to a hardwired preheat temperature that cannot be adjusted.
According to our observation, the Cosori takes around 2-4 minutes to reach 300°F, 3-5 minutes for 325°F, 4-6 minutes for 350°F, and 6-8 minutes for 400°F. When preheating is finished, the oven will beep several times and the display will flash once every minute. You’ll need to press start to initiate cooking or the cooking function will be canceled after 10 minutes.
Thanks to the light toggle button, you have full control over when to turn the light on and off. The door can rest open at a 70° angle to allow food to cool inside the oven. Opening the door doesn’t stop the heating elements or the interior light.
The oven turns off automatically after 30 minutes of no interaction. Nonetheless, we still suggest unplugging it after use for safety reasons.
The Cosori’s EvenRapid Tech™ is advertised to reduce cooking time by 30% thanks to increased heat circulation. Suffice to say, it met our expectations with fast cooking times and even surface caramelization (except on our Pizza test).
Cleanability





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 Cosori’s exterior and interior are made of stainless steel, so they’re usually easy to clean. However, the interior doesn’t have a non-stick coating, so the grease from our whole roasted chicken test led to some extremely stubborn stains on the cooking chamber’s ceiling. We couldn’t completely remove them even after brushing them with a paste of baking soda and water.
The rotisserie forks and rod as well as the rotisserie bracket and the baking pan developed equally stubborn stains. On the bright side, it wasn’t difficult to clean caramelized bits of food from the air fryer basket despite the fishnet design.
The grease on the other walls and around the fan cavity was easy to clean. We were worried that grease might splash into the fan cavity, though.
We were able to easily remove fallen food scraps thanks to the removable crumb tray. However, we still had to tilt the oven to get them all out.
