Is 1200 watts enough for a 2.2 cu ft microwave?

Yes. 1200 W is on the higher end for countertop microwaves and is well matched to a cavity this size. It heats faster than the 900 to 1000 W units common in smaller models.

Will a 2.2 cu ft microwave fit on my counter?

Measure first. A 2.2 cu ft countertop unit is roughly 20 to 24 inches wide and deep, so it needs a deep, sturdy counter with clearance for the door swing and vents. It is not a compact model.

Does it have sensor cooking or preset programs?

No. It offers 10 power levels and a turntable, but no sensor cooking, convection or inverter. You set time and power yourself.

Is the turntable dishwasher safe?

The glass turntable is typically hand-wash only, and the roller ring should be wiped rather than soaked. Check the manual before putting any part in the dishwasher.

How does it compare with a 1.1 cu ft, 1000 W microwave?

It offers roughly double the capacity and about 20 percent more power, so it heats larger portions more evenly. The trade-off is a much bigger footprint and a plainer feature set.
