Bests & Worsts Reviews from Amazon

I bought one of these from Amazon in Nov-2010 and liked it so much I bought a second one for my buddy in May-2011. While the new one functions the same as the first, it does not appear to be an authentic product. It is not labeled with "j/Fit" on the end, it is a little shorter, the surface is rougher, and the styrofoam seems to have more voids in it. When I asked Amazon if this were authentic or counterfeit, they did not respond to my question but refunded me a few dollars. While foam rollers are great for self-massage and releasing sore muscles, the cautious consumer might not want to pay a premium for this particular item.
