Easy to assemble. Smooth and quiet - so far.
I get a much better workout on this than the old Nordic track ski machine it replaces.
Comfortable to use (except for the sweating).
Speakers are tinny, you'll want to use your ear buds.
I'm careful about pulling on the handles. I have to lean in a bit or the machine rocks.
We are small people less than 175 pounds and it work great for us.
