I love this brush! With a permanent retainer, getting a clean-feeling mouth is hard work, but this brush does a great job! It's not loud and annoying like most brushes and after two months the bristles still look and feel brand new. The design is sleek and beautiful also.
I also like that the vibration of the toothbrush doesn't make my nose itch (just a me problem?).
When thinking about what I could improve on this toothbrush, I would change where the power button is. Because it's close to the head, I get my finger all toothpaste-y trying to turn it off. Yes, I brush my teeth like an animal, I am aware. However, I also understand it's where it is for a reason, and rinsing my finger off with the toothbrush is no hassle.
Bottom Line: Yes, I would recommend this to a friend
