The small screen it had was open and broken. But since I don't care about the screen, I didn't return it.

Good and useful, it takes up no space at all and provides satisfactory exercise. Indeed, it needs to be secured against something stable - e.g. a wall - in order not to move when used, but this is easily addressed. It is worth its money. I do not have an opinion yet on its durability over time.

Very good.
We bought it six months ago and it hasn't had any problems.
The resistance adjustment is useful.
I thought it would be a bit uncomfortable, but it's fine.
It's easy to fold and fits under the bed.
The only negative thing is that it needs to be leaned against something so it doesn't move away from the user.

Excellent for the money it costs, the resistance is satisfactory and the assembly is easy!
The only flaw is that it needs some support so that it does not slip during use (against a wall or someone else holding it).

Sturdy construction, with well-adjustable resistance. Folds for easy storage. Reliable company in the fitness equipment manufacturing. I have also purchased their rowing machine, which I am very satisfied with.
