A little better than okay
I ordered this for my sister, and this is what she had to say:  She wanted it because she thought it would be exfoliating.  The bumpy side feels really nice but she was unsure of it's purpose outside of a general massage.  The scrubbing side of it also felt great, but she didn't trust that is was actually cleansing her back because the bristles are so soft.  She wishes it were longer; it doesn't stretch so she was limited in her range of motion while cleansing her back.  After using this body brush she said she still felt like she needed to follow up with a wash cloth to ensure that her body was cleansed to her liking.
