I was fully satisfied with the two kits of 2 meters, fast delivery, stick perfectly, work, etc. I start by 3 meters. I should not have because on one hand he does not at all unlike the other two and the power supply is not working. Too bad, I wish contact you to solve the problem without going through the comments, but you do not give us other possibilities for communication using an existing button usually in our order tracking "Contact Seller" .. .
