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.

I received a sample of this product for a review and I hadn`t thought it would be much better or different than the name brand electronic toothbrush that I already had but it really was. I love all the settings `clean, white and gum care` and I have tried them all but I tend to choose `white` with a whitening toothpaste and the difference shows. The Sonicare does not just brighten the shade of white that my teeth are but it gives them a surface shine. After I used the toothbrush once I had that smooth teeth feeling like you have after you`ve been for a dentist cleaning. I already floss and use and an electric toothbrush but I don`t think I'll use anything but the Sonicare from now on. It tickled a little bit the first time I used the Sonicare but I got used to it after a couple of uses. I want to buy another one for my spouse because I feel like it gives a better, cleaner result and I feel weird having something that works so much better and not being able to share it with my family.

This is a great tooth brush and cleans wonderfully but let me tell you about the battery life on this thing! When I first opened it, I put it on the charger for about 24 hours before using. Now I only have to charge it once a year!!! Pretty incredible!

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

[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.

[This review was collected as part of a promotion.] Great product, holds charge very well! This was important to me and I was impressed with this. I also think another thing this product does well is provide high autonomy without being over complex. The settings are more than enough while also not being way too complex or confusing.

I love the fresh clean feeling after brushing with the 6100. But I am disappointed that it already needs to be replaced / serviced at two months of having it. I also had to change the the toothbrush brush head (I purchased the C3 heads and used one of those first). When I put on the toothbrush head that came with my 6100 it didn’t fit on the metal shaft. It was very loose and would fall off. The brush was also louder than usual and it sounds like a rattle / something is loose in the unit. I contact customer support to get help with my issue and they were quick and efficient to help me out. Now I’m just waiting on my replacement handle.

What happened to $2 toothbrushes? Now they cost over $100 (plus about $40 per year for brush heads)! Well, my dentist says I need it and now that I have (nearly) all crowns (fake teeth) in my mouth, I guess he's right. :-( Anyway, this thing has a chip in the brush head so I sure hope nobody hacks my toothbrush! They might turn it into a chain saw (ouch). Well this thing vibrates so much it feels like a chain saw, but I guess it's getting rid of all that plaque and calculus stuff. One thing I can say is that my gums are improving, so I guess that's a good thing. :-)

FEATURES: I received this product in exchange for my unbiased opinion. Two things I liked immediately about this toothbrush were a higher vibration frequency and smaller brush head design than my previous electronic toothbrush (a competitor`s). I find it easier to position the brush where I want it. RESULTS: I have a small chip on a tooth where I normally get some coffee staining and right away I saw that this new toothbrush has definitely caused the staining to decrease! TECHNOLOGY: I noticed a mark at the base of where the head plugs onto the toothbrush handle and was surprised to find that the toothbrush can detect which brush head is attached. This will allow the toothbrush to monitor use and let us know when it is time to replace it. Since my partner brushes more frequently than I, this feature will make it easy to know when it is time for a new brush head. Overall, I am very satisfied with this product and plan to continue using it.

I had this toothbrush as a Christmas gift and I love it so much. I use it everyday since I got it. However, the problem happened couple days ago is when I was using it and it made loud very noisy. I also do research and I've known that I need to change the brush head every 3 months. But I've been using it only 1.5 months and got this problem. A little disappointed for this cuties toothbrush.
