I ordered 12 of these units and while they took a little bit to come in, when they did I was very impressed with the quality. They seem to be very well built (solid mechanisms and interface). The installation was straight forward and simple (and the instructions were very clear and complete). I would recommend these units (to me, they seem at least as good if not superior to retail available pieces that you could get at a big-box store in the US).
