Hi everybody. My name is Jeff and I have had a bad run of luck with Total Knee Replacements. I've had 5 TKR's and an amputation (above the knee) in a 2.5 year spread. I bought an almost new Pride 300 chair. I'm waiting on a set of new batteries before I use it. I'm a skilled electronics tech and a Amateur Radio Operator (KJ4RWH) I hope to find some tips & tricks to keep things running smoothly.
