A compact, affordably priced microwave that handles reheating and defrosting well on a small counter, though one report of it heating without the start button pressed is worth weighing against mostly positive feedback.

Overview
A 0.7 cubic foot, 700 watt countertop microwave from Chefman with 10 power levels, three one-touch presets for popcorn, beverages, and leftovers, two defrost settings, and a child safety lock.
This is a small-footprint microwave aimed at dorm rooms, offices, or secondary kitchen spaces rather than a household's main unit, and most reviewers bought it for exactly that use. One buyer's account of the unit powering on and heating without a cook time being set is a safety issue worth reading before purchase, even though the majority of reviews describe reliable daily use.
- 700W with 10 power levels
- Three one-touch cooking presets
- Two defrost settings
- Child safety lock and mute button
Who it's for
Anyone needing a small microwave for a compact counter, office, or dorm, particularly if quiet operation and simple presets matter more than a large interior. Less suited to households wanting a full-size main microwave, given the 0.7 cubic foot capacity.
What buyers say
From Amazon customer reviews.
Most reviewers who bought this for a small counter or office report it working well, being easy to clean, and priced fairly for the size. One buyer described the microwave powering on and heating on its own without a cook time set or the start button pressed, which is a safety concern worth weighing against the largely positive feedback.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact size fits small counters and offices
- Mute button silences beep tones
- Simple one-touch presets for popcorn, beverages, and leftovers
- Child safety lock on the door handle
Performance notes
At 700 watts and 10 adjustable power levels, this is built for straightforward reheating and defrosting rather than full cooking, which matches how most reviewers describe using it. The mute button silences the beep tones for anyone reheating late at night or trying not to wake a household, and the child safety lock requires pulling up on the handle to open the door.
