Great Workout, beats the fitness center.
We have had our 3.15 for four years now, and it is still going strong showing little wear, and provides us with a great workout. No standing in line at the fitness center waiting for a machine.
We purchased the all the components and it is well worth the investment.
I am 6'6" and 260lbs. My wife, Judy is 5'4" and 140lbs. it works easily and well for both of us.
