I have tried so many electric toothbrushes and wasted so much money on them. This would be another let down, in my opinion. I love Oral B brand and the style and durability of this product is good but I just feel like the electronic toothbrushes do not clean my teeth efficiently enough. I think if you want a good brushing you need to use your own "elbow grease" and manually brush them. The prices on this product was ridiculous for the results I was given. No more electronic toothbrushes for me. Performance/Cleaning The toothbrush itself performs as it says it should as far as how it spins, the power behind it and the battery life of the unit. As far as feeling like my teeth/mouth received the equivalent to an in office cleaning...not even close! I do not feel it cleaned well. I manually brushed my teeth afterwards, every time. Durability The toothbrush itself is very durable. It stayed highly functional and the battery life seems great.
