The Sharp R-410LK is a family-size microwave unit serving as a black version of the more immaculate, stainless steel R-408LS. Like its peer, this unit also holds 23 total automatic settings, each designed to melt, soften, or warm a popular food item. Included are six automatic cook, six reheat, and four defrost options. There is also a key just for popcorn heating, as well as MinutePlus technology—the 1 button cooks for 1 minute, 2 for 2 minutes, etc.
