Product appeared quite similar to one I'd tried at a campground rec room, so I was hopeful it would be useful to keep up regular minimum cardio workouts while traveling and the reviews on the Overstock website sounded generally positive and promising. Unfortunately, I totally regret this purchase. The biggest disappointment is that the stepping action is only smooth within a very short range of motion. Also. as the pistons warm up, the smell is, well, very irritating even in a room with lots of ventilation. I've given the effort over three weeks to see if these problems might smooth out with use but, no---A Bad Buy!
