We chose this mirror because the controls are in the corner rather than center when horizontal; we wanted to install vertically to increase illusion of higher ceiling. 
Arrived faster than promised and in very secure packaging. The mirror itself looks very elegant and the reflection is free of distortion.  It appears to be made well and everything works as advertised. We wired it into a switch and it maintains the previous settings so we can leave it on the right color and brightness to match our sconces. 
Concerns: No acrylic diffuser on the sides allows you to see the LED light strips. 
The defogger button is red when off while the other buttons are blue during normal operation. This should be reversed so that the defogger button is blue when off and red when on and heated. 
Overall, we love the mirror and hope to enjoy it for years to come!
