[This review was collected as part of a promotion.] My wife and I love using this toothbrush because it is simple and easy to use, which makes it reliable.
[This review was collected as part of a promotion.] I bought my first Sonic years ago and it was great. After years of use the battery started to fail so I bought my second one. It worked great for about 8 months and the internal 30 second timer started to fail. So I bought the 4100 series. When I opened the box I found that I had to go back to town and buy a 110 V charging adapter because one was not included. After getting back home, right out of the box the 30 second internal timer did not work all the time on this model. After buying three of your products it seems like the reliability of your products are decreasing while to price of your products are increasing. I'll do more research and shopping around before buying another one. I have always trusted the Phillips products but now I'm having second thoughts.
[This review was collected as part of a promotion.] I previously used another “mail order” electric toothbrush and thought it was fine, but what a difference using the 4100 series. My teeth feel better and it has made a real difference in my dental care.
[This review was collected as part of a promotion.] I’ve tried electric toothbrushes in the past, but none gave me a better cleaning than this one does!
J'ai acheté cette brosse sur recommandation de ma dentiste mais j'avais un doute quand à l'efficacité d'un brossage avec ce type d'appareil. Vraiment étonnée du résultat, c'est vraiment performant.
