Bests & Worsts Reviews from Amazon

Just want to say about the few people posting pictures of the "bruising"- that is not technically a bruise, it is what's called petechiae. And it's one of the main reasons I bought this roller. This particular roller does a great job at not only rolling the deeper, taught muscle tissues out but also stimulates and breaks up scar tissue and the myofascia. If you bruise like some of those pictures after only a few minutes of use I would highly recommend having someone gua sha your back because petechiae occurs when there is stagnant blood that can be pushed through the compromised capillary walls and it settles in the capillary bed where it is then reabsorbed by the body and this stimulation of circulation increases the anti-inflammatory, pain-reduction, immune system functions in the body. As opposed to a bruise which is when healthy capillaries are ruptured through blunt force causing blood to soak into the tissue. So I give this roller 5 stars because it does what I bought it to do. If you're looking for more muscle rolling less circulation increasing and myofacia stimulating I would look into a roller with a smoother surface.
