See video. Worked great the first 30 days. After day 30, the remote communication with the lights went funky. Several colors were reversed with other buttons. So I could never sync it with the other set I had strung up.I had wanted about 50 feet. So I bought one 32 foot string and one of these 16 foot strings. That means 2 remotes. But oh well. I could just hit green on both remotes and both sets would turn green. Or blue. Etc.But after 30 days, the 16 foot string started doing colors other than what I was pushing. So I can never get all 3 strings to be blue, green, orange. Etc. When one is blue, the other defaults to green. When one is green the other defaults to blue. No matter what I push on the remote.
