Overview
Cosmo's COS-BIM22SSB is a 24 inch, 2.2 cu. ft. stainless steel microwave built for countertop use or cabinet installation with an optional trim kit. It runs at 1200 watts across 11 power levels and adds a smart sensor with six cook presets.
Reviewers most often mention it replacing a failed built-in unit, including one that swapped out a broken Wolf microwave. The trim kit for a flush cabinet look is sold separately under part number COS-30BIMTK, so factor that into the budget if a built-in finish is the goal. Its 16.5 inch turntable and interior light suit a full dinner plate rather than just mugs and bowls.
- 1200 watts across 11 power levels
- 2.2 cu. ft. interior, 16.5 in. turntable
- 24.4 x 13.6 x 19.6 in. exterior footprint
- Optional COS-30BIMTK trim kit for cabinet builds
Who it's for
This suits a kitchen remodel where either a countertop microwave or a cabinet-integrated one works, since the same unit covers both with the optional trim kit. Buyers who want a microwave that ships ready to build in without extra parts should look elsewhere.
What buyers say
From Amazon customer reviews.
Buyers frequently praise the install, several calling it as clean as a professional job, and like the quiet operation, the popcorn preset, and the smart sensor's auto reheat. One owner who has run it for years with three teenagers in the house calls it sturdy. A single reviewer reported the microwave would not power off and had to cut the breaker to unplug it, and another found the child lock unlock sequence annoying.
Strengths and trade-offs
Drawn from this product's published specifications.
- Doubles as countertop or built-in unit
- Smart sensor adjusts to food moisture
- Six one-touch presets for common foods
- Large digital display with clock and timer
- Trim kit for built-in look sold separately
- One reviewer found the child lock feature awkward
- One reported unit would not power off
Performance notes
Power is adjustable across 11 levels from the 1200 watt magnetron, and the smart sensor is meant to judge doneness by reading moisture and heat rather than relying on a fixed timer. Six touch presets, popcorn, potato, pizza, frozen veggies, beverages and dinner plates, cover common single-button jobs. A removable 16.5 inch glass turntable and interior light are standard.
