This is a beautiful cabinet! Mirrored on the inside as well as out. The glass shelves lock into place securely and are very adjustable. When you surface mount it, there are mirrored strips on the sides as well. It looks lovely on the wall. Installation was simple and the cabinet stays very securely in place. We bought two for our small bathroom and all the glass makes it seem much brighter. I expected quality from Kohler and I wasn't disappointed!
