Got the lights for my son's teen-room makeover. They stuck to the wall on new paint really well, great adhesion (in fact I am worried they will remove the paint if I take them off, but not planning to do that anytime soon). As another buyer mentioned, they are white strips so go better in a white room than black strips. When we first turned them on they were only showing 3 colours and the remote wasn't turning the lights off, but I contacted Judy at customer support and she was super responsive and helpful. Immediately shipped me a replacement controller and remote, and followed up, now they are working perfectly. The iPhone app works too. I quote my son this morning "Mum, I set my lights to change colour when I clap". I guess they are keeping him entertained during Melbourne lockdown remote schooling! I also bought some 4-pin RGB LED light connectors from Amazon, and they worked to join two sections together. Anyway, these are fun lights and look great. I think we will get a few more sets for around the house.
