The toothbrush is too small to be effective. Perhaps it was designed for a child, but it is much smaller than the battery operated Sonic toothbrush that I am currently using. Could there be a brush like the toothbrush battery operated and not like the small one included with this product?
No, I would not recommend this to a friend.

We are sorry to see that you are not completely satisfied with the Flossing Brush Heads. We do have larger Flossing Brush Heads available. You can order them here: https://www.waterpik.com/oral-health/tips-accessories/SFFB-2EW/
I like the compact head. I have a small mouth so having this option is important to me. Big brushes usually cut up the back of my mouth. I also feel like you can concentrate on each tooth with the size of the head.
