[This review was collected as part of a promotion.] I bought this to replace an older model and I am so glad I did. My teeth definitely look and feel clean, and my dentist agrees. I love the quadrant timer so that I can be sure to brush my entire mouth.

[This review was collected as part of a promotion.] I was surprised at first by how the brush performed and sounded. It truly is sonic. It has greatly improved my oral cleaning procedure for both morning and before bedtime. This toothbrush makes me feel like I am healthier - that my whole mouth is clean, not just my teeth. Brushing with the ProtectiveClean 6100 gives me a great sense of confidence with my health. I am very, very, happy with this brush!

[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!!!

I have used sonicare for years, and personally love the product itself and it's performance. My problem is the turn on and off button always disintegrates in less than a year, causing the toothbrush not to turn on or off properly, so your forced to buy another one. For the price of this toothbrush, it should not need to be replaced in less than a year. Three years in a row! Phillip sonicare, please address the issue of the on off button disintegrating due to the fabric it's made out of.

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.] This is my third Philips brush and it works so well. I had my previous brush for ten years and it started to wear out a bit. Once I started using my ne one I noticed a big difference in my teeth. Cleaner, smoother and stay clean longer. Best brush on the market!

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.

I always had electric toothbrushes from Philips. Last one I bought lasted me 4 years. This one I bought, after one day, the middle silver part starting peeling .. where the did quality go? Or did I get a defected one. So upset about this. For the money you pay, this shouldn't have happened

We have used Philips Sonic care for years and have never experienced what happened with this one. This last one we bought didn't last at all, mine broke the piece that hold the brush after 1 month of use and my husband's just did the same. It never happened anything like that with any of our past toothbrushes.
