I received this toothbrush as a gift, and I'll admit that I was a little skeptical at first about a toothbrush that cost over $100. I usually spend $5 at most on my toothbrushes and tend to prefer the battery-powered variety. I opened up the box and was using my toothbrush within a few minutes, thanks to the Quick Start instructions included. I was amazed at how clean my mouth felt after I used this toothbrush! You don't have to apply a lot of pressure either, which is good for people who have sensitive teeth or gums. I would definitely have to say this is the best toothbrush out there on the market...
