[This review was collected as part of a promotion.] I really love the 4100. This is the second one I have had. I love that it is quiet, and I like the timer with the 30 sec markers, but I can't get used to the pressure sensor buzzing - it really bothers me. The charge lasts for a long time - great for travel. At end of life it is almost impossible to take apart to remove the battery. That absolutely is a design flaw and needs changing. I seriously cut up my hand trying to break down the old one to get to the battery for safe disposal. The charger should come with a plug not a USB connector.
[This review was collected as part of a promotion.] I was very pleased with the product. Having used the product for several weeks and like the clean felling it leaves in my mouth. If for some reason it doesn't get used, my mouth feels crusty.
[This review was collected as part of a promotion.] I have used a Phillips sonicare since inception and this model has been super disappointing. The vibration is too strong and this model does not allow any change in intensity.
No, I would not recommend this to a friend.

These product are great until they decide to last only 2 years and then break. There is apparently a problem with a screw becoming loose, and that causes the vibration to completely break. I've had 2 that both have broken right after the 2 year mark... funny enough that their "warranty" lasts 2 years. I'd recommend going OralB given I have a couple family members that have had their OralB brushes for 10+ years.

[This review was collected as part of a promotion.] Timing and pressure are fine. It is a little hard to get the proper motion on the back of the teeth as the brush moves side to side and usually with toothbrush I do up and down movement. Battery life is good and recharging is good.
[This review was collected as part of a promotion.] This is my 4th 4100 Series toothbrush since each of the first three had batteries that stopped charging or working. I am really hoping that this one lasts longer than 10 months. I enjoy the toothbrush but just want it to last.
[This review was collected as part of a promotion.] It actually doesn’t work consistently. Sometimes it only has very light.vibration and usually increases while I am brushing. I’d like a replacement.
