I bought it in May 2021 and today, November 2022, it broke. Suddenly it goes all the way down. I lift it up and after 5 minutes it goes down again.

I received it normally, it is what I expected, a simple and economical shock absorber, it may last 1-2 years if it holds up well. EDIT: It started to decline on its own in the first 2 months, it also lost a small amount of something like grease, fortunately not in a place to stain. At the first opportunity, I will go for a new decent chair worth 200E+

I bought it for its price. After 9 months of almost daily use, it started to sag a little as soon as I sit on it. I am waiting to see how long it will take for it to sag enough to need replacement.

It goes down on its own a few points when I sit. Annoying, it will get beaten and thrown away... no matter how much trouble the process is.

It is not suitable for heavy weight. After a month, the chair started rocking like a boat, but that's not its fault. It only costs 7 euros. It's my fault for choosing something so cheap.

Chair damper at a very good purchase price, mediocre in terms of quality, but after 3 months it started to sit on its own.
