As for me, I acquired the book "a pain-body" (which is excellent) and I needed a massage roller, essential to the fulfillment of several years. I did not want to put a fortune in a scroll, and unfortunately I found that most of the proposed products are expensive. Even that proposed by the author of the book, from its online store. Too bad it does not offer many products, quality and different prices to suit every pocket ...
I finally found this, and I ordered based on the two previous reviews. After using it for a month I am able to say that 5 stars are absolutely deserved!
