The most important thing, okay the two most important things, where that the machine be quiet and that I not hurt myself (because it seems like when I exercise I end up with an injury).
Very quiet, and the motion is so smooth! I started slow and now I've picked up minutes and I'm pushing harder and it just feels good.
The machine is developing a few barely perceptible noises (not really noises, just sort of subtle knocks I can almost feel through the handles-my husband can't feel them). But all the reviews I read when I was researching on which machine to buy say that you can adjust the little sounds out by tightening or loosening screws, so I'm not worried.
Really pleased. The size is right and the machine feels very solid.
