Very well, so far. We have done it with Niles IC, Speakercraft EZC10, and AMX, and so far (knock, knock) no problems. Definitely looks cleaner and cuts down on the warranty service calls to reattach unstuck, stray flashers. Racks look really good. Unfortunately, we cannot put them inside Cable Boxes that do not belong to the customer. Comcast tends to get a bit testy about us opening their equipment!! Go figure.
