[This review was collected as part of a promotion.] I've been enjoying my 5100 Sonic for awhile now, and figured I'd get the smart toothbrush for my sibling. The timed featured helps make sure they and their specials needs take the time to properly brush their teeth. The 4100 Series is an excellent value for that task.
[This review was collected as part of a promotion.] I do not have complaints about the 4100 but am giving it less than 5 stars by comparison to a higher end SonicPro. The more expensive version has more options/settings. However, for the price difference, which is huge, the 4100 is my preferred choice.
This is my second phillips electric toothbrush. The first one was great and lasted a long time and this one seems very good also. This one also seems sturdy and it is comfortable and easy to use and my dentist says it does a good job.
[This review was collected as part of a promotion.] My teeth feel cleaner than when I brush with a manual toothbrush. I especially like the timer feature and pressure sensor. I loved the color selections in store. Battery life is excellent!
