Overview
A 1.2 cubic foot countertop microwave with a 12.4 inch turntable, 1000 watts of output, 13 auto-cook menus and a mute function to silence the beep.
- 1.2 cu ft interior, 1000W output
- 13 auto-cook sensor menus
- Two-step child lock
- Mute function silences the beep
Who it's for
Suits kitchens with a tight height clearance or anyone wanting quiet operation and a dedicated 30-second reheat button. Less useful if you need maximum interior capacity for family-size dishes.
What buyers say
From Amazon customer reviews.
Reviewers repeatedly call the microwave quiet, easy to set up and appreciate the mute function for silencing the beep entirely. The 30-second reheat button is highlighted as the most-used feature, and one reviewer noted their unit's box was labeled 1.1 cubic feet rather than the 1.2 cubic feet in the listing, though it still fit their needs well.
Strengths and trade-offs
Drawn from this product's published specifications.
- Runs quietly compared to other microwaves reviewers have owned
- Mute function fully silences the beep
- Fits into tight cabinet openings around 12.5 inches tall
- Dedicated 30-second reheat button
- Box capacity label differed from the listing
- Compact interior suits small households more than large-batch cooking
Performance notes
Reviewers consistently call it quiet in operation and note the mute function actually silences the end-of-cycle beep, unlike some competitors that only lower the volume. The 30-second quick-add button gets singled out as the most-used feature for reheating.
