great
I prefer the oscillating movement.  This is a great brush.  The head is small enough to reach absolutely everywhere, and on a full charge it's powerful enough to feel like you're flossing too!  We bought them at Amazon for around $12, a promo price that comes around every once in a while.  At that price it's barely more than a disposable battery brush, but far more effective in my opinion.  Also the charger is very compact, so the footprint on the bathroom counter is not even an issue.
