[This review was collected as part of a promotion.] The 4100 does not work properly. This is the second one that I had it won't vibrate when brushing. I do not recommend this model. With that said Philip did replace it with the 5100 and there is no comparison in brushes. Highly recommend the 5100 series.

[This review was collected as part of a promotion.] My dentist suggested I try an electric toothbrush. At 85 I'm pretty well set on my ways, but I thought I'd give it a try. It took a few days to get used to the feel, but now I realize its the best thing I've done for my mouth hygiene. My teeth and tongue are cleaner and coffee stains are gone (I drink a lot of coffee). This brush has no "bells and whistles", just a 30 second alert to change your quadrant. Its easy to use and outperforms any convectional toothbrush.
Poor quality. Almost fell apart. Motor is weak and noisy
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] My wife and I really like our new toothbrushes. They do an excellent job of cleaning and polishing. Sure glad we purchased them!
[This review was collected as part of a promotion.] Honestly, I didn't think I'd like this at first. I've never used an electronic toothbrush and it felt very weird at first. The roof of my mouth was so ticklish that I could barely tolerate it on the Inside of my upper teeth. But in time I got used to it and I now love it.
[This review was collected as part of a promotion.] I've been using Philips Sonic toothbrushes for years, various models, and like them a lot. My previous toothbrush was a 6100. The 4100 works fine and cost less, a good value. It's pink, which is fun. Keeps my teeth in good shape, which is the main point.
