NordicTrack Revitalize 2.0 Inversion System —
As far as being built strong and stable it gets an A+. The directions were somewhat confusing, but still very simple to build. The 2.0 does exactly what it is designed to do, take it slow and easy at first, untill you see how much your body will take. A pain free back was reason enough to write a comment. I walk a lot and spend too much time on my feet, this helps greatly.
