What makes the microwave drawer so exceptional is its flexibility and ergonomics. The drawer pulls out, and you access the heating cavity from the top (versus front), reducing bending.  There are several brands that offer microwave drawers with almost exact features:

1.0 - 1.2 cubic feet capacityFits a 7" tall cup or 20oz. cup / 9"x13" pan950-1000 watts10 - 11 settings with sensor cookingDigital LCD screen with Open and Close buttons and Child Safety Lock

Sure, you can place a countertop or built-in microwave under a counter, but you have to bend down to access the cavity and controls - not ideal!  However, the microwave drawer is an excellent way to get design flexibility and ergonomic features.   Let’s take a look at the brands and specifics. There are several brands who have a microwave drawer, but they are all made by Sharp. Sharp holds several patents on its design, so there are only slight differences in the appearance of the front panel and features in other brands.   Unique to Sharp is the use of a handle and the offering of a white front.
