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.
