Review (2/5): Not worth spending any $
I got these so my mom (who has one working arm and one paralyzed) could more easily spread the shampoo over her whole head in the shower. It is easy for her to hold in one hand and use, but the "bristles" are not very flexible and you have to press really hard for them to move at all. In the end it's harsh and uncomfortable for the scalp and feels better to used fingers.
