overall, am very pleased with product. super easy to put together. it is easy to maneuver around my small office if i need to. doesn't take up too much space. levels are sufficient. was thinking only 10 levels might not be that good, but level 10 kicks my butt, and i am in pretty good shape. speakers don't seem to work, but i really don't care about that. and when i place my heals on the outer edges of the foot pad the machine makes a very annoying knocking sound. if my feet are in the center of the foot pad ....as smooth as silk. forces me to have perfect form (i tend to walk like a duck, so want to workout the same way).
also, i might just need to tighten some screws....overall, good product for the price and would buy again.
