I really love this LED strip. I attached it to the back of my tv and out makes me love my place at night. The USB could be plugged into the tv, but this didn't work for me when tv was off so I ran constant power to the light strip. The adhesive take was super easy to install, however I did make some mistakes at first. I should have cleaned the TV and I almost peeled the protection off instead of the take. Anything, it still worked great and I didn't need to read directions.  Love most of the light modes too, however the default one is pretty annoying. Anything, overall - 5 stars
