Overview
A kitchenette counter or dorm corner gets a jet black retro microwave with a bright LED display and touch buttons. Preset programs cover defrost, pizza, popcorn, potatoes and veggies alongside a timer.
Style and a short list of presets are the selling points for anyone who reheats leftovers and cooks popcorn. Power is modest, and the listing does not describe a turntable or interior size beyond capacity.
Who it's for
Singles, couples and shared spaces that mostly reheat food will find the power adequate. Larger households, or anyone needing convection or a built-in install, should skip it.
Pros and cons
- Retro design in jet black
- Preset programs for common foods
- Bright LED display
- Modest power for dense foods
- Turntable not described
- Countertop use only
Performance notes
Lower wattage stretches cooking times, especially for frozen or dense dishes, so stirring partway through helps. The presets set time and power for the named foods, and the five power levels allow gentler heating than full output.
