Overview
Six preset buttons and 700 watts of power make the Black+Decker EM720CB7 a basic 0.7 cubic foot countertop microwave built for reheating and defrosting rather than combi cooking.
This is a straightforward reheat-and-defrost microwave, not a combi unit - it has no air fryer, convection or bake mode, despite some retailer review sections mixing in feedback from Black+Decker's fancier combo models. Its interior is small at 0.7 cu ft, which keeps the countertop footprint compact but limits it to single plates rather than large casserole dishes. One buyer's unit lost venting function and accumulated steam under the turntable at about six weeks in, then ran into a slow multi-step warranty process.
- 700W with 10 power settings
- 10-inch removable glass turntable
- Large LED digital display
- Push-button door release
Who it's for
A dorm room, small kitchen or break room where reheating and defrosting is the whole job is exactly what this fits. It's the wrong choice if you want air frying, convection baking or any function beyond a standard microwave - that's a different Black+Decker model.
What buyers say
From Amazon customer reviews.
One long-term buyer of this exact 0.7 cu ft model reports the venting fan stopped working around six weeks in, trapping steam under the turntable, and describes the warranty claim process as slow and confusing. A separate buyer says the control panel buttons failed one by one after about three years of use. Feedback on ease of use and quiet operation is otherwise positive, though some of that feedback appears to describe Black+Decker's larger air-fryer combo models rather than this basic unit.
Strengths and trade-offs
Drawn from this product's published specifications.
- Six preset buttons for common reheat jobs
- Compact 0.7 cu ft footprint
- Child safety lock included
- Quiet operation reported by owners
- No air fry, convection or bake modes
- Warranty claims process reported as slow
- Control panel buttons can fail after a few years
Performance notes
Ten power levels and six preset buttons handle common reheat jobs by adjusting time and power automatically rather than requiring you to guess settings. The push-button door release and child safety lock are the extent of its extra features; there's no sensor cooking beyond the presets, so results depend on portion size matching what the buttons expect.
