0.7 cu. ft. models fit standard plates and are ideal for small kitchens or dorms. Ensure the turntable diameter accommodates your dishes.
Look for intuitive buttons and auto-cook menus for common tasks. Digital displays and child lock are nice extras.
Stainless steel or black exteriors are durable. Check door hinges and button feel, as cheap materials may feel flimsy.
Some microwaves hum during operation. Our picks are quieter than average, but expect a typical low buzz.
ECO mode reduces standby power consumption. Models with this feature save energy when not in use.

Wipe interior with damp cloth after each use. For stuck-on food, heat a bowl of water with lemon slices for 1 minute to loosen grime.
Don't run empty, use metal containers, or microwave sealed eggs. Use microwave-safe cookware only.
Check turntable roller ring for debris. Clean air vents to prevent overheating. Replace if sparking or unusual noises occur.
We found that 700-watt microwaves heat reasonably well for most daily tasks, but cooking time is slightly longer than higher-wattage models. The trade-off is lower cost and smaller footprint.
For even heating, let food rest after microwaving and stir mid-cycle if possible. Use a microwave cover to reduce splatter.
