  • Extremely cool! With the money!
Size: 13.7FT for 45"-65" TV
I have had it almost a month and really enjoy it so far! It’s pretty reactive to what is going on and there is a bunch of different settings for movies or games and color variations. I do wish the lights we a little bit brighter but this item still gets a five star review.

  • waste of money, doesn't fit. doesn't light up to match the screen colors
Size: 10.5FT for 32"-50" TV
My TV is 50 inch, I purchased the 32-50 inch kit, and it doesn't fit properly. Also, complete waste of money. The sensor does nothing to match the picture/colors on the screen. It lights up random colors. i suggest NOT WASTING your hard earned MONEY on this garbage.

  • No info about the app to control the lights??
Size: 10.5FT for 32"-50" TV
The media could not be loaded. The lights are appropriately timed with what is happening on screen and I like that, but they are very vibrant compared to what is on the TV and the colors rarely match when I am not watching something with vibrant colors. I see a lot of people taking about an app in the comments, but I did not see any information about an app to download or how to change the settings on the lights. I’m not sure if someone can comment on my review or if the company will respond, but I would like to know how to download the app so I can adjust the settings ... show more
