[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.] 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.] Compared to the two previous 3100 toothbrushes (which stopped working in a short time, and i had to return), I love this 4100! This is even better than the sonicare toothbrush which I'd been using for years! .I recommend the 4100 wholeheartedly. Thank you!
[This review was collected as part of a promotion.] I purchased this product in early December 2025 and immediately charged the toothbrush. As of today, January 18th, I have yet to recharge the battery. I also like the slim design as it fits comfortably in my hand while brushing my teeth. It also has a nice feature that will cause the unit to give a gentle beep when I’m brushing too hard.
[This review was collected as part of a promotion.] I love my toothbrush, it performs great, my teeth always feel clean, it is super quiet, and i love how it has a built in timer for each quadrant of my mouth.
[This review was collected as part of a promotion.] After years of using my original Sonic electric toothbrush I thought it was time to get a newer model. The 4100 series is lighter weight and thinner than my original Sonic and it took a few days to get used to the difference.
[This review was collected as part of a promotion.] I received this Sonicare as a gift - one I requested for my last Sonicare was decades old and no longer held a charge. This newest model (and I wanted the pink) is so lightweight with all the great features of the original PLUS the light indicator for the battery.
