Review (5/5): Nice toothbrush
I've had the toothbrush for over 2 months now and it works great. The battery life may appear short at first but it will improve after your second set.
A little bit of water did get through to the battery housing, but did not cause an issue. I dry it every time the batteries are replaced.
Final note, I believe it is as effective in cleaning as my non-battery Sonicare.
