As you'll see in the video, you get a lot of LED's for your money, but not a lot of reliability. The LED's often don't light the way you expect them too, or sometimes not at all, unless you hit the remote control a bunch of times. Reviews online range from 'amazing' to 'crap'. I think it all boils down to how much luck you have with the set you get. After doing the video below, I bought a second set with a better remote control and it does work better. (There's a link below.) There's a huge variety of sets available on Amazon, but from my experience you should buy the 'waterproof' version, (which merely means they have a protective plastic covering) make sure you buy the 5050 LED's (they're brighter than the 3030 LED's, and can be dimmed), and make sure your set includes the power supply. Some sets don't which means you'll have no way to plug it into ACpower. And I'd pick RGBW or RGBWW. (They add "White" or "Warm White" to the Red, Green, Blue, RGB color scheme.) Watch my video for more tips on what to look for when buying LED strips and what problems you might have. Also be prepared to find an additional way to hold the LED strip in place. The sticky backing doesn't really hold well. at all. Mine stayed up for about 20 minutes!
And there's a ton of reviews on Amazon with lots of good information from people who installed these kits.

This is the first kit I bought had the 24 key remote control/receiver which may use some of the same codes as your regular TV remote. That means when you change channels or volume, etc. your LED lights may change color or turn on or off. That set was $21.88 when I checked on 7/22/16:
This is the second set I bought that I found to be more reliable because of the 44 key remote/receiver (vs. 24 key version). So far my TV remote has not affected the LED light strip. It was $28.98 on Amazon at the link below. (As of 7/22/16) RGBW is red, green, blue + cool white - RGBWW is +warm white. Either choice is the same price.
