We purchased both the 30-inc hand 48-inch wide models.  Installation went well since we have basic tools and a level, although we used heavier anchors and added screws at wall studs for each.  The cabinets may slide, especially the smaller model, if the the top brackets are not set at maximum width, but an extra screw under the cabinet fixed that.  Happy with the quality and to have mirrors on both sides of the doors.
