They work on any yoyo that takes hubstacks.  
But they can cause a really bad wobble, on some yoyos  
such as the PGM

Can you be specific? Z-stacks work on any yoyo that comes stock with hubstacks. However if it doesn’t, like the Supernova, Boss, most plastics, and some versions of the Genesis and Catalyst, and others, you cannot use them.

1: They work on any compatible yoyo that uses an A-sized bearing for the stack, and as long as there is enough space in the rim. I think that’s just YYF for now.

2: No. Let me know after you get done hubstacking a Protostar, MVP, Northstar and a Dynasty.

3: They won’t work on Magic YoYO as they use a different sized bearing. I’m not sure what my Duncan MoMentuM uses for the stack bearing but it has Z-type stacks. My Epic uses Ta-Tas which are the same, but different.

I found they just get stuck on smaller YYF’s. 888, Skyline, etc.
