The product is excellent

[This review was collected as part of a promotion.] Philips 4100 electric toothbrush is a solid choice for anyone looking for an easy upgrade from a manual toothbrush. It does a great job of cleaning teeth, leaving them feeling noticeably smoother and fresher after each use.

Good vibration, feels like it's actually cleaning the teeth. Ease of use. Vibration noise is much quieter than previous models too, great improvement in this model. Battery lasts a much longer time too, also a great improvement. Very happy with this product. Was a good purchase for me.

5 out of 5 stars review

Seller Verified Purchase

[This review was collected as part of a promotion.] I had a Quip toothbrush before this one. I thought it was good, but I kept having various service issues like batteries stuck, metallic paint peeling off in the holder. I had enough, and was looking for a replacement when I found this Sonic. After my first use, I realized how much cleaner my teeth felt. What an improvement!
