Overview
GE's stainless steel countertop microwave pairs a 2.0 cubic foot interior with a 1200-watt output, sensor cooking that adjusts time and power automatically, and a two-step child lock meant for shared kitchens like dorms or apartments.
The unit uses weight-and-time defrost, meaning you enter the food's weight and it calculates the defrost cycle rather than guessing at a preset. One buyer who contacted GE directly found the interior cavity is not stainless steel despite the exterior finish, a distinction worth knowing if that mattered to your purchase decision. The child lock disables with a screwdriver or fingernail if you don't need it in the household.
- Weight-and-time defrost calculates cycles automatically
- One-touch express cooking controls
- Glass turntable for even heating
- Kitchen timer and cooking-complete alarm included
Who it's for
A solid match for anyone upgrading from a smaller or older microwave who wants more interior room and faster heating, including dorm and apartment kitchens given the size. Skip it if you specifically want a stainless interior cavity, since only the exterior is stainless steel.
