This Review Title is Not sure what I expected for the price and the content is: Disappointing. Basically an electric toothbrush with a spike instead of a brush. You could probably get the same result with a fixed steel tool. Good thing is they include one which is nice, but odd they include something that shows your product doesn’t work very well !.There are other information for this review, one is This reviewer did purchase it and the other is 4 people think this review is helpful.
