[This review was collected as part of a promotion.] I replaced an older Sonicare toothbrush. This one is smaller and the vibration when using it is less, so it's more comfortable, though it took a little getting used to. I do wish the charging cord came with a plug and not just a USB-C end.
[This review was collected as part of a promotion.] The 4100 series is great at cleaning my teeth , and I don't feel like I'm wearing my gums out while doing it. A definite upgrade in oral care and toothbrushes. I should have purchased one a long time ago.
[This review was collected as part of a promotion.] I needed a newer one so I got this as a Christmas gift. I am very happy with it. Has two clean settings and leaves your mouth feeling clean and it tells you when to switch. I have charged it once since January .
[This review was collected as part of a promotion.] Great features. Long battery life. Bought two of these to ensure better dental care. Pleased with the action of the brush, the beeps to change area being cleaned, ergonomics and overall level of noise.
[This review was collected as part of a promotion.] Purchased the 4100 series sonic toothbrush for both my husband and I and we love it! The toothbrush has 2 speed settings, an automatic timer, and a very long lasting battery. We highly recommend!
