DO NOT BUY THIS PRODUCT!!! I bought 50 of them to sell at my business and all of them are defective and the lights will turn on by themselves and the gesture of the hand will also change by itself randomly. Also, most other remote controls will interfere will this product such as TV remotes and remotes for lamps and electronics. I spent $500 on these for my business and every single customer returned the product and this supplier still won't issue me a refund. This product is completely defective and a waste of time and money with zero chance of getting your money back after you send it. Save yourself the trouble and don't purchase from this supplier because you will not get a refund and you will most likely get a defective product.
