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 finally made the switch to an electric toothbrush about a month ago. I originally had the Oral-B 8000 and it was too bulky, too loud, just too much. So I exchanged it for a Philips Sonicare ProtectiveClean 6100 and I’ve never loved brushing more! I love the three levels of intensities and that I can adjust the timing of brushing by selecting a different mode. The battery lasts me about 10 days before it starts telling me it’s dying. And even then, I can use it another 4 or 5 before it’s time to charge it. Today I had a dental cleaning and my hygienist kept commenting on how nice my gums look and how clean my teeth are, that there was virtually nothing in terms of tartar or plaque. I’m so glad I decided to finally up my brushing game with an electric brush.

[This review was collected as part of a promotion.] I received a free sample for a Philips 6100 protective clean electric toothbrush in exchange for my opinion. I loved this toothbrush. Overall it was easy to use and having the three brushing modes is ideal for me because It gave me the option to brush for a longer or shorter time. I felt my overall gum health was better after only a week of use. My favorite feature is the easy start feature which over time increases the power to help your teeth and gums get used to using a electric toothbrush. I highly recommend this product to anyone who is looking for an easy to use high quality electric toothbrush.

I am now on my second replacement for this product. The metal bar that connects to the toothbrush heads keeps coming loose leading to a loud and terrible experience. I used to have a Diamond Clean that randomly died after 5 years so I bought this when I was in a pinch. It has been 2 terrible years

I received this product in exchange for my unbiased opinion. I would give the Philips ProtectiveClean 6100 Sonicare 5 stars. I have been using Sonicare and years and this model works as well as previous versions but has a couple of new features that I really like. I found the design of the Sonicare to be sleek and easy to use. I appreciate the three modes that you can easily switch between `clean`, `white` and `gum care`. I think it will take at least a month to see if there is a difference in each of these modes but it`s nice to be able to choose. I mostly used the white mode and felt that worked very well for me. I also like that the brush head is very easy to attach and remove. This allows you to clean the bottom of the brush head. This design is much improved from previous versions that would allow lots of `gunk` to build up on the inside of the brush head which was difficult to clean. My favorite feature of this toothbrush is the Brush head replacement reminder. This smart brush heads use a microchip to synch with the handle and will alert you with a light on the handle when it`s time to replace the brush head. I really appreciate this feature because I never remember when to it`s time to change this brush head. Another very useful feature is the battery light that indicates the status of the battery life. There are four different colors/beeps that tell you if the toothbrush if fully charged or has no brushing sessions left and needs to be charged. Overall I`m very happy with this toothbrush and feel like the new features are a definite improvement. I would highly recommend this toothbrush for ease of use and helpful features.

I received this product in exchange for my unbiased opinion. What I like about this Philips Sonicare toothbrush is that it's a well made toothbrush. The first thing I noticed is that it looks and feels like a high quality toothbrush. It came charged, so I could use it right away. The instructions are easy to understand. My favorite feature is the quadpacer. So that you brush all of your teeth for the same amount of time, it has an internal timer and will beep and make a brief pause to let you know when it's time to brush the next area. It has different intetvals for each brushing mode. The are 3 brushing modes,which are clean mode, white mode, and gum care mode. It lets you know when the brush head needs to be replaced. It also has a pressure sensor that lets you know if you're brushing too hard. Overall, I like the toothbrush very much. My only critique would be that since I have very sensitive teeth, initially it was a bit strong and took a little getting used to compared to a regular toothbrush. It's so much better than a regular toothbrush, though. I was amazed at how much better my teeth and mouth feel after brushing with the sonicare compared to a regular toothbrush.

My dentist recommended I use a sonicare toothbrush years ago. I purchased a different electric toothbrush without sonic technology at a much lesser price, thinking it would be just as effective in improving my overall dental health. I received a free sample of this Philips toothbrush in exchange for this review. The product came already charged and I enjoyed getting to use it right away. I quickly discovered that this toothbrush removes more plaque and whitens my teeth better than any other toothbrush I've used before. It did take some time getting used to the intense sonicare vibrations, as well as the fact that it is louder than my previous electric toothbrush. However, I am well accustomed to it now. My favorite feature is the gum care setting as I have very sensitive gums that are prone to bleeding when brushing. Thanks in part to the pressure sensor, the bristles are extremely gentle on my teeth and dental work, causing no gum irritation at all. I also love that I can actually see the microbubbles working between my teeth and around my orthodontics, helping me get the deep clean I desire. I appreciate the Brushsync replacement reminder as well, because I no longer have to guess when my brush head needs replacement. Overall, I think this Philips sonicare toothbrush is a wonderful product, and I highly recommend it to anyone looking to upgrade their oral care routine.

I received a free unit for product testing to review, but this toothbrush exceeded expectations of what a powered toothbrush can do. The most impressive features were the quadpacer and the pressure sensitivity. It was very helpful to know that I may have been brushing too hard at times, and the brush pulses when too much force is being used. Similarly the quadpacer is a great reminder to brush each area of your mouth equally instead of guesstimating while doing it manually. Although, I would have liked some additional time added for tongue cleaning. It`s great for teeth cleaning and breaking the mouth into quadrants and areas, but would have to restart to add additional tongue brushing. Teeth felt cleaner after each brush. Have only used it the brush for about 10 days so haven`t seen much in the sense of whitening so I can`t speak to that impact. The lighting on the brush can be bright. The replacement heads are more expensive. When brushing, I seemed to gleek more if my mouth wasn`t fully closed. All in all, very pleased with the brush. Interested to see if the whitening improves and how the next dental check up goes after using this brush extensively.

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 review was collected as part of a promotion.] Instructions are deficient in that there is no guidance as to the optimal setting. I've heard from some others to keep the setting at the low end and from others to raise it to as high a setting as is comfortable.
