The remote control does not come with a battery.
Not very accurate, but the effect is cool. Well, what more can you expect for this price.
Great purchase, the app connects well with the headband, but the headband is not connected or compatible with Google Home, so you can't control it with voice commands, but it works very well from the Propriétaire app. The only drawback is that it's not bright enough, so more LEDs would be needed on the strip. I give it 5 stars because the effect is really great and it will definitely impress those around you. It's easy to install, it's plug and play. I was worried that the camera would be too visible, but it's okay!

Sometimes it doesn't display the colors from the screen or changes the colors very late. But it's a great deal for the price.
