[This review was collected as part of a promotion.] I truly like the brush, use it every day and I am impressed with the battery life. I would of given five stars if it was not for the cheap case that does not close and stay close. The latch does not stay put. Which is quite annoying.

[This review was collected as part of a promotion.] I definitely get a much better cleaning with this electric toothbrush over my previous manual toothbrush.

I received Philips Sonicare Protective Clean 6100 Sonic electric toothbrush two months ago as a gift and I love it. I have traveled with it several times now. I love the travel case and the battery life is great. I used it for a week without having to charge it. At first when I started using it, it seemed very intense even on the lowest setting, but now I have become a custom to the vibration. My teeth are smother and seem to be whiter. I have tried the whiting button and the gum button once each but stay with the general setting to brush my teeth. As I was told, don't turn it on unless it is in your mouth, it can splatter. It is a little messier than a traditional tooth brush, but worth the time and effort to use the Philips Sonicare Protective Clean 6100 Sonic electric toothbrush. Thank you, Philips for making a great product in a fun color!

This new sonicare model is much better than the older one I had. My teeth feel dentist-clean after every brushing. The 2 minute timer in it is very helpful, too, so all of my teeth get brushed the same length of time. My only complaint is that I found the instructions to be confusing as to the 3 different settings and which brush head to use. It sounds like each setting must use a different kind of brush head, but I need to call customer service and ask someone about this.

I like this model. It keeps my teeth clean and I feel it works really well. However, I bought the same model last year from a "competitor site". It lasted almost exactly one year before it just quit. Once I had this replacement from Walmart, I experimented with the original charger. This new toothbrush worked with the old charger just fine. Obviously, the lithium battery in the previous toothbrush had just died out, after only one year. So, all I can say in honesty is to be aware of the built-in lithium battery life. How can a customer know how long the item has been sitting, prior to purchase? How long will the built-in battery life last? If you research changing the battery, quite frankly, it is a complicated process and not worth the effort!

This is the second Sonicare toothbrush for me. Love the feeling of a clean mouth! No complaints about effectiveness. The handle has been redesigned and is smooth around the entire circumference making it somewhat difficult to hold and control. A different texture on the back of the handle would make it nearly perfect. The rfid chip to track use is interesting but makes for expensive replacement brush heads.

[This review was collected as part of a promotion.] I much prefer the original Philips Sonicare (HX5610 - 150825) but unfortunately it is not manufactured anymore. It is a shame they had to redesign what was a fine product. The new Philips Sonicare (HX369BK - 220606) comes with a much smaller C2 brush head. It does not have the same brushing action as the original Sonicare. The base is very lightweight and not as supportive as the original. You cannot plug the new version into an electrical outlet. You have to buy a USB adapter.

[This review was collected as part of a promotion.] Brand new toothbrush has paused twice while brushing. The brush was still on making a funny noise. Had to turn off and back on to make it work properly. These brushes are too expensive to not be working properly.

My dentist recommended this model plus there are thousands of positive reviews. It's easy to operate, the battery lasts a long time between charges, is waterproof and can be washed off after each use. It does a noticeably good job. Better than brushing by manually. After my dentist visit the other day, they noticed much less tarter and I said I bought the Sonicare brush. It's doing a great job and I highly recommend it!

this 6100 toothbrush definitely provides superior cleaning to my previous sonicare but needs to be charged more frequently-- annoyingly so in my opinion. before purchasing believe i read a product description that promised a 3 week charge with regular use, i am finding that i need to charge every week!?
