I would NEVER use an apex stand for something that long. Disaster waiting to happen.
In reality … that is nonsense.. I have used an Apex for decades, with real keyboards
All with 76 keys... G1000 (41 pounds), G70 (46 pounds), and MediaStation (56 pounds).
If anything the keyboards win the battle against kids (CrabTrap) or drunks (Alfes)..
