Too many features.
First, I like this thing. I think it's great. But there are just too many ridiculous bushing modes. The intensity levels are a great feature, but all the different brushing modes are just silly.<br /><br />Other than that, it cleans well. The brush heads are easy to install and replace. The travel case is nice and things fit nicely. It's not the nicest case and I imagine that the plastic can break with enough reasonable pressure. The toothbrush isn't that stable on the charger. The bristles are soft. The vibrations aren't pleasant but aren't super uncomfortable either. It feels like it's working. And my teeth most importantly felt truly clean when I was done.
