Has a lot of features

Do you really need a $150 toothbrush that talks to your phone? Probably not, but its pretty cool to have!

The does everything it says it does and has a lot of features, much like the brush itself, that Ill not likely use, however, I do like the timer and pressure sensor and the fact that the app keeps track provides feedback on how Im doing.

I like it.
