Hi Fred, I found that post from 3 days ago and realized I had read it before, it just seemed like longer ago than 3 days for some reason. So you have decided that it is helping enough to be worth installing. It is helping you to walk (which is a BIG deal) but not that much with the pain. Mixed bag, but better than not doing it. I hope after you get them installed (this month sometime?) that you have an even better result and that it helps you with your pain too. I am going to be very interested in how you do, and I hope the answer is "fantastic!". My best to you Fred, I am vicariously along with you for the ride. Anticipating all upcoming updates. Hang in there, Hank
