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 minute timer which helps a lot i dont understand the negative feedback with a brush yeah it only has a vpm instead of the vpm expensive sonic brushes but your cost is a fraction of those great buy forthe money
