Bought for my daughter's 15th Bday and they were a hit. We have them going up and over the ceiling so it was a big ask for adhesion and it did start to peel off but we just put a staple gun staple in over the cord. The 10m is 2 x 5m which connect via a short cord (where we staple gunned). If you had it running around a wall adhesion would be 100% fine. She has connected to her her phone (an app?? not sure) and controls and creates the colours from there - better than the remote it comes with.
