I got this for my son before he went off to college. We first tried it at home, and it is wicked cool. Unlike the old color LED lights these have so many colors and combinations of patterns it mesmerizing. We tested the lights by putting them around my TV.  I found myself playing with the lights rather then watching what was on TV. It was easy to use a spare USB port on the TV to power the lights and the remote lets you sit back and play.  When we moved my son in his dorm, we installed the lights around a window. The adhesive on the back worked great to hold the lights securely. He used an old USB block from a phone charger and plugged it into an outlet. If I had not promised it to my son, I would have kept them. I think I will buy another one, a little bigger to be able to surround the whole TV.  You can’t go wrong these, their fun!!
