[This review was collected as part of a promotion.] Please note: I received the product free in exchange for my review. Set-up was extremely easy. The toothbrush came fully charged and ready to use. I could simply press the power button and brush. It did take further reading to learn how to select the desired mode and strength of brushing. There was a quick start guide and another booklet that was more in depth. The quick start guide was not quick to locate, as it was tucked inside other papers. Accessories include a charging base, travel case, brush cap. The charging base plugs into a standard outlet. It is compact to take up minimal counter space. The handle can be put on the base in any direction. Since the connection between the handle and the base was loose I felt it was unstable and tips over easily. My favorite feature was the pressure sensor. If you are applying too much pressure when brushing the brush will make a "buzzing" sound. Features I would like are a wall mount for the charging base and multiple brush head storage for family use. Did like the sonic technology. May sound odd, but I have had other sonic toothbrushes that have made my nose vibrate when using them. Overall, I was pleased with the product. Philips makes a solid, dependable product. If you are looking for an individual sonic toothbrush I would highly recommend it.

I received the ProtectiveClean 6100 Sonicare to review and sample and it by far surpassed my expectations. Not only was this toothbrush easy to handle and operate, but it also provided great quality and functionality. My favorite feature is the auto shut off function that lets me know when to move to a different section to brush. I highly recommend this product if you are looking a toothbrush that is simple to use and efficient in every way.

I received the product free in exchange for my review. I have bought many electric toothbrushes, but I must say the Sonicare 6100 is a great product. There are a lot of features that make it so user friendly. It alerts you if you brush too hard, if you need to replace the head, it buzzes when it's time to change zones in your mouth. I like that you can change the intensity of the brush. It has 3 options to choose from when brushing. I would definitely recommend this product. It is light years ahead of any other electric toothbrush I've bought.

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. :-)

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 brought the 6100 after my 5100 had issue with the head started becoming loose and made a very loud noise. So I bought a 6100 and it has been fine bit the Bluetooth never worked. I really loved using the app with my 5100. But my new 6100 I have never been able to get the Bluetooth to work on it.

My teeth feel cleaner. Best toothbrush I've ever noughy

I always thought my teeth were clean, but WOW.. This toothbrush is amazing and you can tell a difference in your teeth in just a few days.

I definitely felt a cleaner brush when I started using this toothbrush. I used it 5 months and then it quite working. Disappointed.

I should have bought this 40 years ago. The side to side action cleans much better than a spinning electric tooth brush.
