We purchased the larger, 48", version for one bathroom and are very happy with it.  Love the three doors/sections, the mirrors on the inside, the size and look...contemporary but clean looking.  When it came to finding a medicine cabinet for another bathroom, it was a no brainer for us. We selected the 24" version and will be installing it in a few days.  The shipment from Wayfair was delivered on-time and undamaged.  

Pros: Kohler has an unbeatable warranty.  The first medicine cabinet we got was damaged by our contractor.  He chipped one of the mirrors when he installed.  I called Kohler and they sent a replacement to us at no cost and with no questions.  Fantastic!
Cons: More setting for shelf height would be nice.
