I had to calibrate the camera few times to get the perfect colours. But mainly that's cos I kept my camera at the bottom of the TV and could not align it centrally due to my TV design.
Once synced, it works flawlessly. It definitely adds to the TV watching experience. Synced it with Google and now I don't need any remote or button to activate the lights. Fun!
Only issue for me is that it does not pick black/darkness on screen. It instead shows a very faint yellow glow during dark scenes. But not much of a complaint.
Delivery was super quick. I received it in a day as Amazon promised. Really impressed!
PS: Writing the review during daytime, so the video does not look that awesome. Looks much better at night.
