I owned Braun before I got Philips Sonicare. The vibration motion of Philips sonicare is differ from Braun. Braun does circle motion of the bristle, sonicare vibrate the whole body of the brush head. It takes time to get used to the change. I trust others reviews, so I give this a try. Motor wise is quieter, the body smooth for more hygiene even though it does not help much in the shower, so I only use at the sink. Very good price when Sam’s club goes on sales.

At first these were incredibly loud—so loud, there were concerns about them damaging hearing. Then, after about a year, the bottom broke—quit holding the brush tightly. The brush broken and is now even louder. Not worth the money if it’s going to break.

I have gone through two of these in the last 3 years. They simply don't last anymore! I have the older model that first came out and it has lasted like 8 years, yet these new and improved ones are such a disappointment. They start making a very loud noise then the vibration power goes down and the toothbrush becomes useless. I just returned them and were only 6 months old.

Divide the purchase price by two and that is the cost per year you will pay because the product is not built to last. When it starts vibrating loudly it is gone. If it is under warranty Philips may send you a replacement but it will also last less than two years. It's a great toothbrush while it lasts.

This is the 2nd Sonicare model to fail in the last 3 years. This newer generation model is built just well enough to outlast the warranty. Garbage. Because I have brush heads, I'll buy the cheapest model to use them up, then switch to a better quality maker.

[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 the Philips line of brushes since they were recommended to me by my dentist over 12 years ago. I am 62 years old with two small cavities and while I would like to credit genetics, I am sure my continuing use of the Sonicare toothbrushes has helped with my overall dental health and general well being.

[This review was collected as part of a promotion.] I love the phillips sonic tooth brush. This is my third. The last two died after a few years, but long after warranty. The only problem I have is that although this tooth brush is new and I'm using the brush head that came with it, the brush falls off as I'm using it. This just started a couple weeks ago and I've been meaning to contact the company about the warranty. I can still brush with it, but it falls off at least one time, every day. I've taken off the brush head and cleaned both ends, but I don't see anything that would keep it from having a strong placement. I haven't had this happen with your previous tooth brushes. Although my last one didn't seem to have a good seal with any new brush heads after I had used it tge base for a couple years. I thought that maybe I was buying the wrong brush heads, so tried several different types of sonic brush head, but all seemed to have a gap and were wobbly. That said, none if them ever fell off the base while in use. Can you help?

[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.

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.
