Bests & Worsts Reviews from Amazon

This is an update. I paid 60.00 for this toothbrush and now 7 or 8 months later it doesn't work at all. I wrote to the company here on the Amazon site asking for a replacement or a refund (before I wrote this update) and got no reply. So far I am extremely happy with this purchase...much more than I expected actually. It is very cool. It does the quadrant notification thing which I like but it seems a little on the short side so I go around twice.
