Just got this in today from eBay $650 to my door...

It has rollers that go from the head to the tailbone on the back. It squeezes your arms, feet, thighs, and calves with bladders that work pretty well. The controller looks as though it has lots of programmable options. Not sure what you can do yet until I read the manual.
My buddy had one and I was sold after using it once. Went together in 5 minutes. Ran it through a default 20 min "pain relief" cycle and didn't find any issues. Worked just like my friends. Gonna love to hit this before and after riding the cable (or boat).
