this review title is: it is ok quality not sure it is useful though and the content is: 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 have been using it daily since i got it and i am just not sure if it makes any difference to my skin at all.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
