Overview
Retro styling wraps around a genuinely compact 0.9 cu ft microwave here, rated at 800 watts with 12 preset cook settings, 5 power levels and a turn-and-push dial instead of a button panel.
The retro shell is a styling choice layered onto an otherwise basic 0.9 cu ft microwave, and long-term owners describe exactly that: years of dependable reheating with a control dial that has little to go wrong with, aside from normal wear after the better part of a decade.
- 800 watts, 5 power levels
- 12 preset cook settings
- Rotating glass carousel
- LED clock display
Who it's for
Singles, students or anyone with a small kitchen who wants an easy dial-controlled microwave with retro style. Not sized for households regularly heating large casserole dishes.
Pros and cons
- 0.9 cu ft is small for large dishes
- Interior coating can bubble or rust with age
- Occasional dead-on-arrival unit reported
Performance notes
800 watts across 5 power levels and 12 preset cook settings handle typical reheating and light cooking, with a rotating glass carousel evening out hot spots. The turn-and-push dial replaces a button panel entirely, which several long-term owners credit for the unit's durability.
