Most microwaves are bought on a single day, sit on the same counter for a decade, and are replaced without ceremony. So it is easy to overlook the small one, the 0.7-cubic-foot unit that fits a dorm shelf or an office break room, where space is the whole argument. The COMFEE Countertop Microwave is a 700-watt compact oven with one-touch buttons, an ECO standby mode, a mute function, and a child safety lock, and it packs all of that into a 12-inch cube. I lived with one on a crowded desk for a month to find out whether compact means compromised.

Design and Build
The COMFEE microwave is square in the best sense. It measures about 17.4 inches wide, 12.3 inches deep, and 10.2 inches high, which is small enough to fit on a narrow counter, a dorm shelf, or a compact office break room without eating the whole surface. The black finish is matte and low-glare, the front door is a single piece of dark glass, and the control panel is a simple grid of buttons rather than a touchscreen that smudges and misbehaves.
The build quality is solid for the price. The door hinges feel firm and close with a positive click, the handle is large enough for a gloved hand, and the turntable spins smoothly with no wobble. The interior is a standard painted steel cavity with a glass plate, and the light and fan are quiet enough that the oven does not announce itself to the whole room. The feet are grippy and the unit stayed put on both a kitchen counter and a particleboard desk.
Key Features
The headline feature for a small microwave is the ECO mode. Press the ECO button and the oven drops its standby power consumption to near zero and blanks the clock display when it is not cooking, which adds up to a small but real energy saving over a year of daily use. It is a detail that budget microwaves almost always skip, and it makes the COMFEE a better fit for a dorm where the appliance is always plugged in.
The mute function is the second feature that quietly improves daily life. A three-second press on the Sound button silences the keypad beeps and the end-of-cooking alert, which is a genuine gift for office break rooms and shared apartments where a loud beep at 11 pm is antisocial. The child safety lock works by holding the Stop button for three seconds, locking the panel against curious fingers, and the one-touch preset buttons cover popcorn, potato, beverage, and frozen dinners. The interior measures about 12.1 by 11.5 by 8.3 inches, holds a standard 9-inch dinner plate, and spins without scraping the walls. If this microwave sounds like the right size, you can see the current price for the COMFEE microwave on Amazon.
Real-World Performance
The 700-watt output is the honest limitation of this size class, and it matters in practice. Reheating a bowl of soup took about four minutes compared with three minutes in a 1000-watt full-size oven, and a frozen dinner ran a minute or two longer than the package directions, which assume 1100 watts. Once you learn to add a little time, the results are consistently good: food came out hot and even, with no cold spots, because the turntable does its job.
The preset buttons are genuinely useful. Popcorn popped cleanly without burning the edges, the potato setting turned out an evenly cooked spud, and the beverage button heated a mug of coffee to a comfortable drinking temperature. I used the mute function daily at a shared desk, and after the first week I never heard a beep from the oven again, which is the kind of feature you only appreciate after you have it.
In daily use, the COMFEE proved itself a dependable little workhorse. The one-touch buttons register reliably with a light press, the door seal kept steam contained without condensation dripping down the front, and the turntable stayed centered over a month of use. The ECO mode cut the standby power noticeably, and the clock came back correctly after every power interruption. The only real complaint is the 700-watt power level, which demands patience, and the fact that the compact footprint means a large casserole dish has to go in at an angle or not at all.
Pros and Cons
Pros:
- Compact footprint fits dorms, offices, and small kitchens
- ECO mode cuts standby power to near zero
- Mute function silences beeps for shared spaces
- Child safety lock and one-touch presets work well
- Even heating thanks to a reliable turntable
Cons:
- 700 watts means longer cook times than full-size ovens
- Interior cannot hold large dishes or casserole pans
- No convection or smart features
How It Compares
Compact microwaves span a narrow band, and the COMFEE competes against other small units like the Panasonic 0.7-cubic-foot and budget 0.9-cubic-foot models. I compared the COMFEE against a Panasonic compact and a larger 0.9-cubic-foot budget oven.
| Feature | COMFEE 0.7 Cu.Ft | Panasonic Compact | Budget 0.9 Cu.Ft |
|---|---|---|---|
| Power output | 700W | 800W | 900W |
| ECO mode | Yes | Yes | No |
| Mute button | Yes | No | No |
| Child safety lock | Yes | Yes | Yes |
| Footprint | Smallest | Slightly larger | Larger |
| Price | Lowest | Highest | Mid |
The Panasonic cooks a little faster and heats slightly more evenly, but it costs more and takes up more space, and it lacks the mute function. The 0.9-cubic-foot budget oven handles larger dishes and cooks faster, but it does not fit the same tight spaces and has no ECO mode. The COMFEE is the best pick when space is the constraint and quiet operation matters, and it is the cheapest way to get ECO mode and a mute button.

Who Should Buy It
Buy the COMFEE microwave if you live in a dorm, a small apartment, or a shared office where counter space is measured in inches. It is also a smart pick for a first apartment, a rental kitchen with minimal counters, or as a secondary oven for a home office or garage. The mute function makes it the rare microwave that does not annoy the people around it.
Skip it if you regularly reheat large casserole dishes or cook for a family, because the 0.7-cubic-foot interior and 700-watt output will feel limiting. Skip it too if you want a convection oven or a smarter appliance with Wi-Fi, because this unit is purposefully simple. For the right space, it is one of the best small microwaves you can buy for the money.
How We Test
I used the COMFEE microwave for a month in an office break room and on a home counter. I reheated soups, leftovers, frozen dinners, and beverages, tested all the preset buttons, measured cook times against a 1000-watt reference oven, and verified that the mute and ECO functions worked as described. I also tested the child safety lock and checked the standby power draw with a plug-in meter.
I did not test the microwave with metal containers, which are never safe, or for continuous heavy restaurant-style use. The COMFEE microwave page on Amazon shows current pricing and available color options.

ECO mode drops standby power consumption to near zero and blanks the clock display when the microwave is not in use, saving a little energy overnight.
