I have been using this tooth brush for a couple of years, I wore one out and bought another one. I like how I can brush all of my teeth! on top and bottom. I brush behind my teeth to get the plaque. One time my husband said it did not help, so I tried your hand held brush and I got plaque behind my teeth in the front of my teeth. So I went back to my battery oral B brush I brush for about two minutes. and when I get done my teeth feel like I just got my teeth cleaned. I could sell these for you in the store because how hipe I get about the brush. I bought my husband one of those brushes the real expensive one and I did try his and my teeth did not feel clean, and it was timed two minutes. I love my Oral B brush.
My dentist suggested I should get an electric toothbrush about 5 years ago so I bought this one and it has helped so much with the improvement of my gums. Love It!!!!
