Personally, I bought it for a 61-key keyboard and I am satisfied. I intentionally chose the lever lock for the legs of the stand because I find it more user-friendly and effective than others.
Since the stand has a single metal "leg", it is stable mainly for lightweight instruments. I tried an 88-key electric piano weighing 12 kilograms and it was not as stable during intense playing. So, for something heavier and larger, it is better to choose a stand with a double metal "leg".
The stand comes in a rectangular cardboard box and is assembled quite easily, it just requires a careful look at the diagram on how to insert the 4 metal elements where the stand rests. If someone sees the photo on skroutz, they will notice that both the bottom and top parts are facing each other in reverse.
