This is my third Sonicare toothbrush purchased over the last 10 years. They have all performed well and lasted a reasonably long time. I find the replacement brushes much too expensive and have resorted to generic brush heads for the last several years. This new model follows this path as it uses heads with embedded chips to monitor the life of the head. They are exorbitantly too expensive for my budget so I doubt that I will ever buy them. I do like the choices I have for brushing and I also like the warning I get if I am brushing too hard. My dentist likes the results of my using this system also.

[This review was collected as part of a promotion.] I have been using Sonicare products for over 20 years and I love them. This particular model isn't as nice as some previous ones I've had though. It doesn't have the rubber type grip surface to help hold the brush & maneuver the head. It also "glitches" which I'm guessing is the brushing too hard feature??? From my past products, it feels to me like it's time to move to next quadrant... Anyway, I love the results!!! Since I started using Sonicare, my dental checkups have been sooo much better, thank you!!!

[This review was collected as part of a promotion.] My dental hygienist recommended this toothbrush so I thought I would give it a try. I was a little hesitant at first because of the price but I am glad I took the plunge. There are three different settings and it is up to you on what one to use. I started on Number one but leave it on two now. I love the timer on it, it lets you know every 30 seconds so it is easy to time your brushing, and it automatically shuts off. Definitely worth the money

[This review was collected as part of a promotion.] Cleans teeth well. Have only used the "clean" function. See no reason to try the others. Supposed to notify user every thirty seconds to change quadrants. Usually, only get one notification after 90 seconds. Not a big deal or I would have sent it back. Battery life is as advertised, about two weeks. Quiet. Like the size and feel.

[This review was collected as part of a promotion.] If you want the cleanest clean when brushing your teeth, Sonic Electric Toothbrushes are the only option. I have been using one for many years and it is satisfaction guaranteed for me. I get great reports from my dentist and dental hygienist every time. Remember your dental health is tied in with your overall health and that begins with Sonicare Toothbrushes!

My 5100 failed under warranty. While waiting for a replacement I decided to upgrade to the 6100 which has now failed a month from purchase at the same point: the brush attachment post. So now I have a 5100 replacement that I have not used and a 6100 that I paid for that has now failed. Absolutely pathetic quality control.

the Sonic toothbrush does a great job of cleaning and maintaining teeth, especially when you don't have the dexterity to use a regular brush. Unfortunately, we continue to replace them with 1, 2, and 2.5 years, just after warranty expires. They just don't last as long as you would expect for such an expensive toothbrush.

[This review was collected as part of a promotion.] This is a good, inexpensive model which odes not rotate.Instead, it just vibrates. Due to frequent vibration per minute, the metal mile that the toothbrush head goes into may get loosen in a few years. Thus, it must be used with care. I had to get mine replaced through warranty with no cost.

[This review was collected as part of a promotion.] Been using Sonicare for over 20 yrs and love its cleaning action and ease of usage, no wrist movement required!. I also really like timer function that beeps every 30 seconds to prompt quadrant change, and shuts off automatically after two minutes. The base lasts a long time, after 20+ years I'm only on my 3rd one. The metal stem of the base of my 2nd one was loose and not working properly. Since I was within the 1 yr warranty period Phillips replaced it with no problem. The price has gotten more reasonable for the brush replacements over the years.

Won't charge after a few weeks. One of the toothbrushes suddenly stopped charging.
