I see why it was on sale! It does it's job (let you move inside!) but absolutely the basic bare minimum. It has no electronic incline adjustment, no suspension (so no give as u run), and it is very "tiny". By that I mean the width and length are much smaller than you imagine with a treadmill - great for small places, but probably not ideal for actual regular use.
I'm content - I'll only use it when it's icky outside and it's safer than my old one. But I definitely and thankful I did not pay full price!
