They can be kind of a pain to put up on the wall and you'll go through a lot of Command Strips placing them, but the result is 100% worth the effort. They make both a great accent light and a suitable replacement for a table lamp if you're pressed for space. There are nearly endless configurations within the app and if none of them suit your taste, creating your own light show is a breeze.
I was kinda skeptical about them before purchasing, but after the fact I'm glad that I did and will definitely be buying more in the future.
