Review (4/5): Second Time With This Item
I bought this as a direct replacement of the first one, which was recommended by my dentist. It lasted two years before the battery would no longer hold a charge. That wasn't very good, but I like the way it works, and my checkups have been good since using it - much better than when I was using a manual brush, and that's the bottom line for me. We'll see if this one lasts longer. Amazon's price on sale was about 25% less than Target or Walmart. I find I replace the brush head about twice as frequently (about 6 weeks) as recommended by Oral B. It pays to buy them in bulk at a wholesale club.
