I would like to let you know how much I appreciated the use of your EZ turnbuckle knee device. It really worked well. I used it three times a day for four weeks and my knee is so much better. I had 3 degrees of bend on the first day I used it, and in 20 days I gained 13 degrees and my Dr discharged me. I am 83 years old and now I am able to walk so much better. Thanks again for the use of the device!
