compared to earlier models, this one seems more cheaply made; the tip doesn't sit right within the handle. The handle doesn't sit well within the unit. The pressure is not as easy to control.
No, I would not recommend this to a friend.

The unit works well. It seems to me that the water reservoir should hold more water, based upon the recommendation to spend three seconds at each tooth (by a number of dentists/hygienists). It is not possible to spend that kind of time when trying to hit the front and back of teeth.
