Don't know how I got this product did a review on Amazon and noticed nothing posted here. I'm a physical therapist and we ordered about 20 of the Grid 2.0 they are great. This product is really a foam roller warm up tool or if you are very sore it might get you moving until you can tolerate the Grid 2.0. I like this tool for my forearms, calves and anterior shin muscles the most. [This review was collected as part of a promotion.]
