I take my mini everywhere, work included. I am 30 years old, 6'1, but grew up with immune and muscularskeletal issues, due to the harsh environment of Eastern Europe in the 90s. I was not aware of how far my body was out of alignment until I decided to give the Pso-Rite a try. Today I own most of the Pso-Rite products and use them every day. I have a long way to go but I've dedicated my life to understanding physical therapy and I wouldn't be able to do it without these products because I can study biomechanics in the comfort of my home. An honorary mention is the Pso-Key, because i have found it useful beyond its task. I always have one on me between my fingers, allowing my hands to feel pressure, further stabilizing my wrists, elbow, shoulder, and neck. I hold/squeeze it between different fingers, allowing me to develop muscle memory and proper rotation. My hands, among other parts of the body, never got to fully develop, and have always been numb, weak, and in pain, but for the first time in my life, these problems are starting to go away, I am developing muscle in these areas, and my hands are now significantly larger. It's a lot of work, but I now see the finish line. In fact, I plan on going above and beyond, as for the first time in my life I am becoming athletic. I can say that at 30 years, old I feel better than I did when I was half my age, and I owe so much to the Pso-Rite team.
