I just ordered a kit and everything worked out just fine. I asked a few questions upfront and got a response in a timely manner, then I gave it a go, paid with PayPal and it was delivered in the expected time. The kit included all parts and was even easier to install that I though. I have to say that it took quite a few hours till we had the perfect setup and they work like a charm. After I read all the reviews here it struck me that the claims are posted without a name and the "claimed losses" are questionable. In my opinion I got the product I wanted for the best price you can find out there and I would recommend to order from this site.
