Battery died in 2 1/2 months. I tried all advised debugging methods. It’s not worthy of the Philips Sonicare reputation. I’ve had Sonicare toothbrushes since the late 90’s.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] I love my sonicare toothbrush. It surpasses expectation, and outperforms all other “knockoff” brands I have tried in the past. I also like the fact that Philips brand is extremely transparent about what goes into making their products. I trust the brand. That’s peace of mind worth the extra money.
[This review was collected as part of a promotion.] The quality of the Sonicare brand isn’t anywhere near what it once was. I had purchased a new 4100, a lower end model to be sure, since the one I had bought around 2020 didn’t disappoint. The moment I charged it up and turned it on I knew that the device had been significantly downgraded. It was like brushing my teeth with a toy. I bumped it up to full power, but it was still limping along. Needless to say I returned it. My husband did some surgery on my original 4100 and replaced the battery (not for the faint of heart), but my teeth and I are much happier.

[This review was collected as part of a promotion.] Not too pleased with this product. Don’t get me wrong, I love the Sonic toothbrushes and think they’re wonderful for my teeth. I had purchased the same model but it started to turn on by itself which got very annoying. So, I bought another and this one makes an odd vibration noise sometimes while using it and the detachable brushes don’t seem to lock in —or connect correctly— with the base. Disappointed. Should be a better product for this price.
