Even if you could find some smaller ovens besides the 1-cubic-foot Sharp R-305KS, seems to be doing a fair job. RWithaÂ width of 20 inches and a depth of about 17 inches, the microwave oven can really fit into your kitchen, no matter how small that is. Also, the owner-written reviews are generally good. The not so positive ones revolve around burning smells. The basic microwave oven includes four defrost, six cook and six reheat options, a popcorn button and shortcuts for melting, softening and warming. The compact size adds value to this model.
