This is a great set of LED lights. The app is easy to download and use. You can easily change the colors and create your own custom colors. You can link these to other brands of lights (at least it worked for the other set I have). The adhesive is very sticky but I would suggest cleaning the surface first so it sticks easily and lasts longer. My son uses them around his bed and they are very bright and colorful depending on the color you choose. I would recommend these lights for anyone who wants to use this lights for added color.
