Review title is worth every penney [SEP] Unbeatable! The next best thing to going to your dental hygenist daily.  I have been using the same one for 10 years, never needed to buy a new one.  I switch the brush out every 3 months or so.  I can still remember the epic difference between my regular toothbrush and this. a small amount of toothpaste does a great job. Worth Every Penney, do yourself a favor and get one today.
