I was really excited to give this a try since I've never used an LED strip like this before. I like that you can program it from the app and that it has a self-adhesive. What I didn't like was that I can't control the lights through a custom setting. You also can't set these to flash or do any kind of effects other than switching from color to color. I also found the app setup to be a little confusing but after a few attempts I was able to install it and use it successfully. Over all these are a nice starter to see if you're interested in mood lighting.
