The head is a little on the small side. It doesn't hold.
No, I would not recommend this to a friend.

Hello Kei Kei - We are sorry that you are not satisfied with the SFRB-2EW. Although it is smaller than some toothbrush heads, it does not make it any less effective.

Having flossing built in with my toothbrush makes it so easy to floss as much as I should! Took very little time to master having the water spray between my teeth instead of all over the mirror, counter or myself. Definitely recommend!
