I stepped into the Houston store at the beginning of this Year (2014) a little skeptical about this product, I have seen the infomercial several times and I said to myself that I will give it a try. I was greeted by the personnel and Carlton Sisco offer me his help, he ask me several questions and the reason of me being there, I told him that I was having calf pains, knee pains and back pains, he asked about my job, I'm a machinist and stand on my feet for 12-14 hours a day, he recommended the whole system exerciser ,maintainer and relaxer and he mentioned that if I was not satisfied or that the expected results were not there to bring them back and that he will change them until I will get the results meaning my pains and he mentioned that the products was warranty for life that will not have to pay for replacements any more,I left the store went back to work and follow his instructions to wear the arch supports, within a day or two I noticed the difference my knee and calf pain went away and then back felt better and I was able to work and walk a lot better and pains at all , I wanted to tried them also for running and again no knee or calf pain, I'm totally satisfied with the arch support , I recently went back and got an extra set of arches for my running shoes and also a replacement for my working shoes and at that time Carlton was there and he remembered me when I first came to the store and once again with the same friendly approach he took care of me and recommended to move up on my arch support for my working shoes. I would recommend anyone that suffers from aches and pains give it a try you will feel the difference I know. Alberto
