Review (4/5): good -- but weird -- but good
This is a weird little gadget. Technically, it's been flawless. We plugged it in, we charged it, it worked. Since then, it's continued to work.
The weirdness is in the way it feels. Even at its stronger setting, it's very gentle. I'm used to mashing my brush against my teeth like some kind of barbarian dental hygenist. With this, if I press too hard, it complains.
The real test, though, is its ability to clean my teeth. When I finish using this thing, my teeth feel at least as clean as if I used a manual brush. I feel like they shouldn't, but they do. I'm sure I'll get used to it.
It works. What else is there to say?
