I bought a Flex 940 locally yesterday for my own use, maybe three racquets a month. I haven't used it yet, but I did mount a strung racquet on it just to see. My first impressions are:
That the suspension mounting system is very good and easy to use.
That the turntable is very wobbly. I will try to do something about it (teflon tape? any other ideas?)
The clamps and clamp bases seem solid.
The disk brake is very loose and probably wasn't assembled correctly.
I did search, for and could not find an owners manual somewhere online. Does anyone know where I could find one?
