Thanks to you, Sherri for all your help (You do a great job and are very knowledgeable)! When I first received my JAS, Luke showed me how to use it and he was great… He explained everything to me and I couldn’t believe how much it helped my total knee replacement! I was having a problem bending my knee back and – after using the JAS – I could stretch my leg and bend my knee much better! My doctor released me and I am fine thanks to using the JAS faithfully each day for three times a day. It’s worked great for me!
