Review (5/5): 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.
