Bests & Worsts Reviews from Amazon

I never used plain foam rollers, so I have nothing to compare to. But I like this gadget. I like to stretch/massage my tense back and tight muscles over shoulder blades. Having spikes is clearly an advantage. In fact, I have a 2.5 inch (diameter) 6.5 inch (length) rubber roller with (much thinner obviously) spikes that I have been using for the same purpose. And it was intended for foot massage in principle. So I've been wondering if I could find a bigger roller just like The Rumble Roller. And I did. The only thing is that I can't lie on it lengthwise (to exercise the abs) as I would on a plain roller (sacrum hurts from lying on spikes lengthwise!!) but you can't have it all. An update a few months later - 1) I tried the "plain" foam rollers at the gym finally.. No massage effect for me whatsoever on those ones! 2) I love massaging my calves/hamstrings and even anterior of the hip. I can even massage my deltoid/biceps/triceps. And oh, the buttocks massage rocks! Rolling on my back helps mobilize it. I recommend. Another update - Sept 2011: BTW, mine is regular size, regular firmness (long blue) I am using this roller every single day. It's pretty sturdy. I wonder how long it lasts.. but so far so good! I love it. Now I see that the manufacturer came up with a variation in length and firmness and I am determined to buy a black variant. I need something firmer, for my upper back at least. Footnote - I am accustomed to using all sorts of firm gadgets for rolling; but I suggest that most people start with an original density one! And last remark - to those complaining about the price.. It's cheaper to own this device (hey, you pay once), and learn how to use it, and do so regularly, and listen to your body (and a PT's advice occasionally), than to hope a medic can magically fix you in one visit! Lazy attitude.. Stay well! October 2011: I just got my small black version of the roller. My, this thing rocks! I love it. I'll save the blue one for quads and calves, black one is irreplaceable for the back and buttocks! Note: I guess the manufacturer would put me in their so-called "advanced user" category. Most people, especially those who are not athletes, will probably be satisfied with the less dense version (blue).
