Review (2/5): Don’t waste your money
This may have worked for some people but it didn’t do anything for me. I initially bought to try to take care of any tartar between my teeth. The front of my teeth are pretty tartar free and stain free. But this did nothing but vibrate on my teeth. I wish I would have read all the negative reviews first before buying. The best tools in the purchase were the manual tools. You have to be very careful when using them because they are very sharp and you can easily cut yourself.
