I purchased this as my old Casio display unit no longer worked as newer keyboards needed more space between each tier. So, this beast was ordered and I was surprised how quick and easy it was to put together.
It was only going to be used in the home since I never worked with more than two keyboards but would have no worries using it for gigging. I used a modified Fender Rhodes piano stand which was very heavy duty for holding a fully weighted electric piano. I'm not sure the Jaspers would have really handled the weight even though the paperwork that came with it stated it could. I found the arms a little too flimsy for that but if you are only using it for keyboards (as I did) you won't have a problem.
If used for gigging, it doesn't need to be dismantled if your car/van is long enough as you simply loosen the two end clamps and the whole lot folds flat (as flat as possible).
I have now sold this as well as all my keyboards due to ill-health but if I were looking for a stand for 3+ keyboards, I'd buy another of these in a heartbeat.
