Great find!

Pro:
It's an innovative way to brush your teeth much faster than usual! The normal way of doing it is so slow, you can only do a little part of your teeth at one time, we've all wanted to brush all of the teeth at the same time!

Because it's faster, it's probably easier to keep and stay in the habit

Has a lot of potential for making the teeth cleaner (and feel cleaner with the massages!)

Wireless is great, too, very convenient (this is pure convenience)

Cons:
Doesn't floss all the teeth at once :( I'm asking for too much, but that would be such a dental revolution...

It's really cool but I still have personal skepticism - everyone's mouth is different, can we be so sure it will worked as advertised?
