Has anyone tried one of these and what are the results?

No but kind of want to get one...only concerns I have with them are incline & speed options. Other than that I feel it should be a great expensive machine.

I have it! Love it ! There are 2 ways to set it up- "stepper"- when you walk and step up at the same time, and "treadmill" when you can turn off the stepper part- it is just in incline position.

It does not go flat and it does not go faster then 3.5 mph- those are the draw backs in my opinion.But otherwise I love it!

Can u adjust the incline on it?
