[This review was collected as part of a promotion.] The 4100 is not as robust as the 6100. The 6100 cleans the teeth and gums in a much more robust manner.
[This review was collected as part of a promotion.] I returned the item because the toothbrush didn't fit snug on the base charger.
No, I would not recommend this to a friend.

[This review was collected as part of a promotion.] Great size for grip, speed variations, and battery life. Love my new toothbrush and my boyfriend ended up buying one as well after seeing how great mine is!
[This review was collected as part of a promotion.] My dental hygienist recommended that I purchase an electric toothbrush, so I looked over the offerings, read the reviews, and decided on the Philips 4100 Sonic electric tooth brush. The pulsating action leaves my teeth and gums feeling really clean and my whole mouth feeling refreshed. I've purchased additional brush heads, which have added to the Philips 4100 versatility. And thus far the initial charge shows no signs of losing strength. Terrific product!
[This review was collected as part of a promotion.] I love this toothbrush. I have two of them now. My dentist recommended it because nothing cleans better around teeth that have gum disease. I recommend this toothbrush for cleaner teeth and healthier gums.
