Later, in the mid/late-90s I would sometimes use it with my students.
I just hope the machine can still function while being tilted to about a 50-60 degree angle, in order to slightly increase ball speed. I just want to use it to work on my volleys (contact point, footwork, spacing, etc.) in my basement during winter.
