This Review Title is Nice design - didn't do much though -Returned it and the content is: Nice design but other than that, was not impressed. I found it to be quite painful and didn't see any improvements from what I have been doing with brushing and waterpik. I use a tool to remove plaque that actually worked even better. This plaque remover was quite painful to use. Even on the lower speed. Just not sure about the effectiveness of this product. I returned it..There are other information for this review, one is This reviewer did purchase it and the other is 1 people think this review is helpful.
