[This review was collected as part of a promotion.] I recently switched to the 4100 when the Philips toothbrush I purchased 5 years ago stopped working properly. The 4100 is a significantly better product. It is smaller, and easier to handle than the old one. The power button is recessed in the handle, which makes it harder to accidentally turn off while brushing (that happened several times with the old model). Instead of plugging directly into the wall outlet, the charger base on the 4100 connects to a USB charger.
[This review was collected as part of a promotion.] Toothbrush is good overall, however, it feels very thin/slim in your hand and the brush head is much smaller than I expected. Almost feels like a kids toothbrush.
[This review was collected as part of a promotion.] My dentist recommended that I purchase an electric toothbrush after I had implants done. I couldn’t believe how much cleaner and smoother my teeth felt.
[This review was collected as part of a promotion.] My mouth feels a lot cleaner. Although, using an electric toothbrush is tickling my gums and mouth,so I've been trying to get used to that.

[This review was collected as part of a promotion.] I chose this product because I had great results the last time and the product lasted for years. No regrets, this one works awesome too.
