Overview
A 1200 watt commercial microwave built for high turnover kitchens, with a stainless steel interior, exterior, and door plus 20 programmable memory pads for repeat orders. Suits restaurants and cafes needing consistent, quick reheats rather than home countertop use.
Its 11 power levels and 3-stage cooking let staff queue a defrost step followed by two different cook powers in one program, useful for items that need to thaw before finishing. At 0.7 cubic feet the cavity is sized for individual portions rather than large trays, so it fits a commercial line rather than family size reheating.
- 1200 watts, 0.70 cu ft capacity
- 20 program inputs, 11 power levels
- Express Defrost runs in 3 stages
- Digital display with double quantity button
Who it's for
Suits commercial kitchens, cafes, or break rooms that need fast, repeatable reheats of individual portions and can program settings once for staff to recall. Not intended as a large capacity family microwave.
What buyers say
From Amazon customer reviews.
The one review on record reports the unit arrived damaged, a shipping issue rather than a design flaw described in the text.
Strengths and trade-offs
Drawn from this product's published specifications.
- Stainless steel interior, exterior, and door throughout
- 20 memory pads store repeat settings for staff
- 3-stage cooking chains defrost with two cook powers
- 0.7 cubic foot cavity fits individual portions only
- One buyer received a damaged unit
- No consumer-facing recipe presets, geared toward commercial operators
Performance notes
Selectapower technology provides 11 variable power levels, and the 3-stage programming lets a single memory pad step through defrost, then two separate cook powers in sequence. The Express Defrost function splits thawing into three stages aimed at more even results than a single continuous defrost cycle.
