Review title is great sonic brush for the price [SEP] This brush was recommended to me by my own dentist. He wanted me to try a sonic brush, but avoid paying the very high prices out there. The results so far have been nothing but very clean teeth and gums. There is also a 2 minute timer which helps a lot. I dont understand the negative feedback with a $20 brush. Yeah, it only has a 20,000 vpm instead of the 30,000 vpm expensive sonic brushes... but your cost is a fraction of those. Great buy forthe money.
