Too Bad. So far, I have always been "followers" of Busch & Hunter. But this time we went but wrong. Sure, as a dimmer can be a little buzz. But one of the two-bought has extremely "toned". Now I do not know if this is an isolated incident or not. Two ordered dimmers but for me then 50%. Therefore three star. Delivery and redemption through Amazon exemplary. That makes up for the "construction delay".
