This thread brings a chuckle to me. Not necessarily a happy memory, exactly, but memories nonetheless of one of the more exasperating experiences of my life.
In 1991, I had an ACL reconstruction on my left knee. Being an avid skier, I decided that a Skier's Edge would be a great rehab and recovery tool while I rebuilt my knee and leg. I bought the damned thing new and started using it a lot. Like an hour a day. I liked the workout and I felt that it was really helping me strengthen everything AND it was promoting a motion that I would use come ski season.
Well, my first set of belts lasted maybe three months. I called SE, complained, was sold a new set of belts at half price. Those also lasted 2 or 3 months.
When I called to complain again, I was told that my weight (195# then and now) was too high and I was overpowering the belts. They sent me "heavy duty" belts at regular price. I couldn't tell any difference when installing the HD belts and couldn't tell any difference in use, and those broke as well after a few months of use.
By that time, it was dawning on me that I could bankrupt myself buying new belts for this infernal machine.
When THAT set of belts broke, I had reached my limit. I took the machine out to a farm pond in the country, rowed it out in a little boat, and dumped it over the side. I'd like to think that it still might be providing habitat for the largemouth bass and bluegills that live there, but I think it's far more likely that it rusted into nothingness in a couple of years. As far as I was concerned (and still am) the Skier's Edge was a piece of junk that I would never wish upon a friend.
