Review (3/5): Works, but ergonomics seem off
First the good things. It works. In fact, I found the battery life to be outstanding. I took the toothbrush on a 12 day trip and it lasted that long despite only being rated for 10 days. It cleans your teeth pretty well. I also like the pressure indicator that lets you know if you're pushing too hard. Because it's fully functional, I don't feel like I can give it less than 3 stars. But here's why it doesn't get more.
First, the brush cycle. I've used other electric toothbrushes that also have the concept of a brush cycle, a beep, series of beeps, difference in the brush, whatever, that informs you to switch to a different area of your mouth. This toothbrush has that too and it works. Then it keeps working. The others I've used ran through the full cycle then turned off. This one, just kept going. You have to manually switch it off before it will stop. It's not a big deal since I know what part of my teeth I'm brushing, but it's part of the general behavior that I don't like.
Next, drool. Again, I've used other tooth brushes and I know that you have to maintain a good seal or you'll spray things everywhere and/or drool all over your chest. But with this brush, I was getting drool despite maintaining a good seal. I was very careful and always was leaking. Why exactly? I'm not sure, but I attribute it somehow to the shape or action or ergonomics.
Finally, the easiest to fix, I think the brush is way to strong. If I were to continue using this, I'd need a softer brush.
It might just be me, but I'm just not crazy about it even though it works adequately.
