A solid feel and grip to this model.

[This review was collected as part of a promotion.] I like the grip on this model. This is the 3rd Sonicare toothbrush I've owned. The 2 before had been dropped and the small drive shaft that provides the vibration was knocked loose. Hopefully this one will last longer. This one also seems to be quieter. The 3 speeds are nice. The other nice feature is the confirmation beep when inserting the brush.

Great for sensitive gums

I needed something that is gentle on my gums. I have found oral b in the past not to be. After my last of brand toothbrush died I was worried about finding a new one. This one is even more gentle than my last one %26 yet still cleans really well. I have it on the gentle mode. I'm sure it would be faster/harder in the other modes

Great toothbrush

I was hesitant to spend that kind of money on a toothbrush but the dentist suggested an electric one, specifically Sonicare. I had bought cheap ones in the past and they were very loud and hurt my gums. This one is quiet and is very gentle on my gums and I love it! I'm so glad I chose this one.
