    I have had the sonic toothbrush since it came out in the late 90’s early 2000. I love the sonic toothbrush but found out that the battery life does not last as long. My review of this particular diamond sonic toothbrush receives an average “C” score. Not really worth the $240 I paid for it because it does exactly the same quality cleaning as the lower price toothbrush. You do get the nice glass recharging cup and you can download the app to see if you had missed a spot but honestly if you had to hold your phone and brush your teeth at the same time, that brings a bad habit of wanting to text while driving. I recommend getting the lower price unit from SonicCare.

    Never thought I would pay this much for a toothbrush. You feel like you just left the dentist every time you brush.
