I really like the convenience of not having to charge the brush. I also like the timing feature that keeps me cognizant of the importance of each space along my gums.
When I rinse the brush I am wary about the battery getting wet...it hasn't, however, the gasket surround is not totally leak proof. That being said, the battery has remained dry each change; I believe the changing of the brush on a regular basis prevents the gasket from wearing to a point of breaking down. A bit of ingenuity there!
I do not like the change to the toothpaste!
It is not smooth anymore, more chalky than smooth, and it no longer eases out of the tube. The tube has changed too and once you never left a drop of toothpaste on the lip of the tube...now each and every time there is waste after putting your paste on the brush and it leaves the tube messy - I do not like this change!
Will I keep using the brush?
Yes; but not the toothpaste.
That's my quibble.
Bottom Line: Yes, I would recommend this to a friend
