The Smooth surpased our expectations. It doesn't have all of the bells and whistles of some machines but we don't run that way. It does have a solid feel, a smooth motor, and a quite operation. We got the solid machine we always wanted at a good price. One of the best thing about it is that it is so quiet.
People can talk about like nothing is running at all.
I look so forward to my workouts now. Also I was a bit scared of buying it over the net, but it was great also and so easy. I would definitely recommend it to anybody wanting a treadmill. I am running four eight minute miles per day at a 3 degree incline. There is no belt slippage rattles or squeaks.
