Review (5/5): Great electric toothbrush
If this isn't the standard for electric toothbrushes, it should be. It works very well and I haven't had any leaking issues mentioned in other reviews. As long as you're careful when you rinse it off and dry it afterwards, you won't have any issues either. The refills are a touch expensive, but that's expected.
I will say that the health of my teeth has definitely improved at least a little since I started using this toothbrush.
