The cooking cavity of the LSRM205ST is round (with a two cubic foot capacity), and so can fit a large turntable, as well as large serving dishes. The optional trim kit makes this microwave look like it is built into your kitchen. Though they have features in common, the LSRM205ST differs from the higher cost LSMH207ST in that it is a counter-top model (as opposed to over-the-range), has no defrost pan, has no melt/soften feature, has no night light, and has three sensor cook options (as opposed to seven). The LG LSRM205ST comes with a two year parts and labor warranty.
