Hello everyone, well packaged, one can over 5m, and super light effect, low price but only operated a few seconds the time to try some colors and effect, then you can not operate with the remote control, I disconnected and reconnected, changed stack .. and finally returned the product, it is in repayment. I think like other comment is that the control box bug .. shame! I took on amazon another LED strip 8euros most expensive but with control of 48 functions .. awaiting delivery, no comment from another customer on the product that I chose, in hope not to be disappointed
