These lights are really fun!  We put them on the back of our TV and it makes an awesome colorful glow.  It looks really nice.  We also like them for dance parties!  It is fun to be able to change the colors of the lights and that the lights change color on their own as well.  The only complaints I have are it is hard to turn corners with the lights (recommend just doing a straight line) and the button to change the color of the lights gets stuck sometimes and makes the lights flicker.
