Kurt Kinetic Rock 'N Roll Trainer with PRO Resistance Unit.....any reviews

How is this unit, looks interesting…

I have it. Love it. I use it together with the swiveling KK front riser, and it does feel a bit more natural than having the bike “locked-in” to a mode rigid trainer. Paid a bit over $400 shipped with the rock and roll frame and the heavier flywheel through www.lifestylesport.com early last year.
