It is ok quality,  not sure it is useful though
The quality seems ok, it didnt have any weird smell or anything. One side has thinner bristles, the other one thicker. It is quite short in my opinion so it takes a second of getting used to it in order to use it on your back. I've been using it daily since i got it, and i am just not sure if it makes any difference to my skin at all.
