Review (4/5): The best ever
This brush has been the best ever since it first became available. The original version did not have a timer. The timer on this is a bit annoying and they should either remove it or put continuous as a default setting. The company is ignorant because it does not seem to know what scrubbing means. The timer is equivalent to telling a surgeon to stop scrubbing after two minutes. Scrubbing reduces bacterial count quite a bit but only if one scrubs all soft areas for minimum of 5 minutes including tongue, back of the mouth etc.
