This stand is sturdy and very stable, and doesn't get in the way of your legs and feet, which is great for using pedals.
It's pretty easy to mount, but you need to take your nord keyboard upside down every time for that - not a big problem for me. The first time you mount it is a little more work because you have to screw a permanent support to your keyboard, but then that support stays there (and doesn't prevent you from placing the keyboard on a table top, or any other stand, like you would have before) and subsequent mounting or removal of the legs is very easy.
You can't adjust the height though. The height is that of a real piano's keyboard, which means you'll need a piano seat (or a seat of same height) to play comfortably. Not ideal for sitting on a regular chair - that would be too low. At least for me, and I am 1.69m tall - a rather average Human size I suppose.
Anyway, I would buy it again.
