They are so pretty. Great quality, they look good, i’m not sure about the battery life because I haven’t had them a whole week yet. But the brightness of them and the color is so good they they graduate their colors they go from blue to red to green to yellow and they all do it at a different time with each other. They’re very easy to take off and put back up. Just sit them on top of the wall right on the edge and they hang there. We have really high winds here in North Las Vegas and they have survived the winds that we recently had. They’re very lightweight. The ones I got are brown, And I do wanna say I got 16 lights when I received them one of them was not working. I did as the seller said if anything was wrong with any of them to send them a email and they will replace it so I have one coming to replace it and then they sent an extra run for a spare, and that was done immediately, and I appreciate it. I love my lights.
