The lights itself work great. but I advise you to purchase a better tape to put on when putting these on. I put them all around my small tv and they did not stay on for not even a week. they all came off , so I had to go out and purchase a two sided tape and get them back on other than that they are great. They work amazing and they dance to the music that you play. The only reason i gave them the 4 stars was for the tape they came with other than that they would have gotten the whole five stars.
