The electric cable to the right side mirror has worn through and failed within two years of installation. The wire bends slightly every time you open and close the door.  This does not appear to be an isolated problem from other customer reviews.  Unfortunately, a replacement cable is not available and Kohler has discontinued this model.  

This was an expensive mirror was meant to be used for many years.  It now reminds us every day that this Kohler product is an electrical hazard that sits right above my sink. 

Hugely disappointed in this mirror
