It lasted less than 6 months, it broke in half, it's all plastic and doesn't stay in place, it moves very easily in front due to the plastic.

Quite good, although it is plastic (I have concerns about how long it will last), the packaging it came in was not good and was damaged (I don't know if it was the fault of the shipping company)

Stable, does not slip on tiles, non-slip surface. It does not have an adjustment but its slope is such that it is not needed. Very satisfied with the purchase for me who sits for many hours in the office.
