Review: Completely changed gaming for me - The lights were easy to set up and they look absolutely beautiful. Lots of light customization options with their app so I could tweak levels just to my liking. I can’t play video games anymore without these lights, they truly enhance the experience. Movies and shows pop as well. Definitely worth the purchase.
Review: Absolutely loving this! - What sets this apart is that it uses the feed directly from the receiver—no bulky camera stuck to the top of the TV like other brands. Setup was super easy, and my whole family is obsessed with how much bigger and more immersive it makes the TV feel. I previously had a similar model from another company, and it was just okay. This one, though, looks fantastic—clean, bright, and way more accurate with the colors. The clip I shared is from one of the best scenes in Game of Thrones (Battle of the Blackwater), and this was filmed at 2 PM with the lights on. It looks even brighter and more incredible in a dark room. If you're on the fence, this is the one to get.
