Purchased this product and had it installed in June 2019.  One of the lights flickered and quit working.  Had electrician out to check and diagnose the problem.  The wire between the cabinet and the mirror is a goofy design and now has an internal short.  There appears to be a part number for this cable (#1268722).  Really poorly thought out and very difficult to screw and unscrew the cover.  Apparently the cable is not part of the 5 year warranted Integrated LED components, and is only a 1 year item.  I'd kick it across the street, if it hadn't cost nearly a grand and the lighting in the bathroom was designed around it.   All the other Kohler products didn't disappoint at all.
