Works fine

For the people who complain a few tips. 1. It works on sound. 2. Dont talk or have people talking while using it. 3. Dont have your tv loud. 4. Keep your hands still while in use. I tried showing people at a party and it would not work. Music was blasting. So try to use it in a quiet place and Im sure the results will be better.
