[This review was collected as part of a promotion.] Purchased due to a recommendation from Wirecutter and never looked back. It's everything it reports to be: quiet, powerful and sleek. One thing I noticed early on was that the on off button was the same color as the body so visually it was harder to locate than through feel.
[This review was collected as part of a promotion.] We bought the Philips Sonic 4100 Series electric toothbrush in August after our E Series Philips electric toothbrush began to only work intermittently. We had the E Series for about 15 years and thought it did a very good job cleaning our teeth and gums. The 4100 Series took some getting used to. It feels different in my hand and feels different on our teeth but does feel like it is doing a sufficient job. The next trip to the dentist will tell the story. I also like that there are 2 speeds.
The Sonicare toothbrush is perfect for part of one's oral hygiene care. Does and excellent job of cleaning the teeth and strengthening the gums. Easy to use. Solidly built. One charge lasts a week of brushing (4 times a day). Highly Recommended.
[This review was collected as part of a promotion.] Like this toothbrushing, it functions well. But the button design really needs to be reconsidered, the rubber part easily fell apart after abt 2 years use, and it happens to many customers. I got a replacement cos my warranty still covers, but I would expect an electric toothbrush can last longer than just 2 years.
