Works as advertized. Nice!
I saw lots of negative reviews but figured some people just don't know how to figure out mechanical gadgets. I read the good reviews and was impressed with those reviews.  I purchased the product, it arrived in two days and it works like a charm. Works with your own toothpaste as well!  My front teeth are their normal color after polishing them twice for the first time.  I will use this gadget at least once a week to remove those constant recurring  Coffee Stains. Very happy with this inexpensive polisher.
