I have 4 of these for myself between my primary ones here at my home and 2 at my second home for my wife and I. My dentist had first suggested I buy and use the Sonicare. The reason why I'm adding this review is that my Mom (who's 100) had been given an electric toothbrush that was another brand and wasn't happy with it... not only that, she couldn't easily turn it on & off and was very frustrated.I bought this one for her and she's been thrilled that it not only is easier to use, turn on and off, she loves the method of how it brushes her teeth. This is a great product and I highly recommend! And for an older parent, ease of use!
