At first, I was confused on how to set it up. The adhesion didn't work as well as I liked, had to use quite a lot of blue-tack. The hassle was definitely worth it though! I love this colour so much, it's my favourite and suits my room. I did have trouble because it turned on and it turned off after a while and I couldn't get it to work however after asking questions on here I found out I hadn't really followed the arrows on how to plug them in so remember to do that when installing. Overall happy with my purchase, really love it in my room and fairly priced for what you get. Will purchase more :) The app is also easy to use and it can sync to your music which is a bonus!
