We ordered 2 x 2m or two of these kits. We are fully satisfied since we ordered after receiving another 3m kit from the same seller. The problem is that the new kit came with a damaged power since the LEDs will stop flashing and the IR box does not respond. By testing on the power supplies and enclosures other IR kits everything works perfectly, which led us to see that the problem is with the power supply. Sometimes it works, then after a few minutes, nothing. Our question today is whether it is possible to replace us. Concerning the treatment of the order and delivery: impeccable, fast, nothing to say.
