It is thinner at the base of the shock absorber than the factory one, resulting in not having a big difference from the broken one I had. It is lower, meaning the chair has sunk more at its base compared to the previous one.

Two weeks seems fine.
The installation can be difficult. In the chair, the broken cylinder wouldn't come out of the base no matter how much I hit it with a hammer and lubricants. Eventually, luckily, I had an old base from another chair and this new cylinder fit in easily.

Excellent product, it does what it promises, it is just like in the photo, time will show its quality

It is as I expected, the dimensions are as described, I hope it withstands, that's what matters

The shock absorber has been installed on an old chair for 3 weeks now and it works smoothly. So far, everything is good!

It was purchased and installed on 10/10/2022. So far, it works perfectly. I will come back at a later time regarding its functionality

Very good product, value for money.
I received it in two days, well packaged. I installed it immediately and it works perfectly.

I replaced the original shock absorber that was on the chair. Two weeks of using it and it works perfectly!

I placed it on a chair worth 200 euros, from a well-known furniture chain, which had recommended (not to change the spare part), after a month of use I see that the shock absorber is very good.. After 7 months of use, I can say that it is very good.

Very good build quality. I went from category 3 to 4 and I believe it will last longer than the previous ones.
