Bests & Worsts Reviews from Amazon

As mentioned by others, they are clearly fake once they arrive. They don't have the serial numbers engraved on the bottom, they're missing the little circuit piece as well. In addition, the cut of the bristles is wrong, and the colors are dim. Do not waste your money on these... I didn't realize they were fake until I went to use one. Much to my chagrin. Waste of money, and it's after the return window.
