Query: Low cost and functional

I am pretty happy with this treadmill overall. The assembly was quick and easy. It takes a little getting used to mainly because the incline kind of forces you to walk at a certain pace. But once I adjusted to that, I began really using it and I'd have to say I like it. I would recommend this product for anyone looking for a simple, manual treadmill.
