Good for small spaces.

The Walmart mainstays 700 W microwave is pretty good. It fits a normal size silicone popcorn popper of 5.75 inches. I fit my 10 inch Corelle dinner plate with room to spare. It fits coffee mugs max 6 inches tall. It heats food well, you just have to add one minute to everything. Only thing I would change is to put a handle on the door, this is a flat panel. The cord is length is about 31 inches. Simple to disengage the child lock permanently if you don't need it. No weird noise, it's pretty quiet, you just hear the fan. Nice color choices.

Perfect item for my small kitchen!

This is perfect for my small kitchen. It's just my teenage daughter and I. The size is very accommodating to a regular size dinner plate and something even slightly larger. The microwave is generally easy to use and heats your food in decent timing. My only hang up is remembering to push the lock button before I can open the microwave!

It ain't fancy, but it does the job!

It's a little smaller than my last one, %26 couldn't be much smaller or there's a lot I couldn't cook in it. But it cooks VERY well. At 700 watts it does better than my last microwave, an RCA @ 1000 watts. It cooks evenly, no “hot spots”. Most pleased and at less than $60 it was cheaper than replacing the PART to repair my 10 month old RCA that went kaput!
