For quality control: every bolts knots and rings were already in place, but with delivery 3 sets weren’t twisted enough and fell in the box, which had a bottom hole with delivery. Was lucky nothing was lost.
For potential buyers: this is sturdy piece of equipment, it’s on the heavy side, but it has a handle (big problem with the Stamina Inmotiom e.g) and it stays in place instead of sliding like some other models.
I really appreciate the tether in our office setting so the chair doesn’t roll away while working out.
Last, even the first level makes you work a bit, and the max can be a workout but is not too much. In comparison, other models will start with almost no resistance up to really high resistance. Depends of want you need and want. I really think that one hits the spot
