I’ve had 2 3100 series and the button breaks and you can’t turn it on anymore. Not sure how long it should last. Maybe 3 years is good?

This required a USB block to connect to the wall, 8 times the plug size, which can interfere with a nightlight being connected to the same outlet, adds extra material to landfills. Sonicare saved money but l would choose something else next time.
[This review was collected as part of a promotion.] My teeth feel so clean and mouth invigorated. Takes some getting used to. I can’t imagine being without my Phillips toothbrush. I’ve just spent about an hour searching and re-searching the manual to figure out why my toothbrush suddenly has extra beeps after I finish brushing. Never did find out what it’s trying to tell me. Manual is awkwardly written. A simple “beep code” would raise my rating to 5 stars.
[This review was collected as part of a promotion.] Great brush. However, the handle gets slippery when brushing and sometimes, slips from my hand. Feels like it needs some grooves instead of the smooth plastic. That's why I gave it a 4 rating.
[This review was collected as part of a promotion.] The toothbrush is as advertised. It seems to work well and do the job. I will find out how well when I see the dentist. There was a free brush head offer with the toothbrush. Philips website rejected the code, so no free brush head. Looking at the available brush heads none list the 4100 series as compatible. Makes determining which brush head to buy a bit tricky. Otherwise the toothbrush is fine.
