It’s actually really quiet.
Got one without the resistance bands for the girl a couple years ago, and she loves it. I use it too.
After 2 years, when I’m standing on it, there’s a slight clicky sound on one side, but only when standing, not sitting, and that’s probably just a lubrication issue.
It was the perfect solution for helping her get low-impact exercise (she has fibromyalgia, and we’re baby-stepping her back to better health) in our small apartment.
Highly recommended, although what was said upthread about the short stride length is true. (How could it not be at this size!)
