I bought this smart set of LED light bars by #sylvwin and they work great. I bought a set for my bedroom and saw these and decided I could use a set in my den. They work great and I love the bluetooth connection. These at $55.99 make a great wedding gift or a great Christmas present. With the holidays 3 months away don't let these pass you by. Well worth it as therexare so many modes and so m.j any ways to sync them .
