Bests & Worsts Reviews from Amazon

I have used this for a little over a month and really all back pain is gone. Yes lower back too....I feel like I am 21 again. It works great but the instructions were lacking so let me tell you what I do. You assemble it and get the curve set up on however aggressive(or lowest) you want but I use the least aggressive. I put the widest side next to but and the narrow up on towards the middle of the shoulder blades. I laid on it the first time for 1 minute,,,then roll off and lay flat on my stomach a minute. I did this for three straight days. The results at that time was well strange,,it felt loose and yet their was some phantom pain I guess associated with it...you know when you expect pain. I worked up to 3 minutes of stretching twice a week and still roll off and let rest for a minute before getting up. No pain...hope this helps.
