This is really easy to use. When attaching to a surface, make sure you only peel the blue film off, not the entire sticky bit like I tried.  After that, it's a piece of cake to install on a clean surface.  I've set it on one color permanently, but it can cycle through all the colors instead. The remote is a nice feature as well, but after the initial setting it doesn't get much use.  Definitely adds another level to my tv viewing.
