For a changing setup, a great addition!
The toms are basicly hovering in air before the wing nut is tightened. I can loosen the wing nut, and the toms stay "floating" in place. Then I can set them to a different height or rotate the stand easily.
I changed the original ball L-rods 12,7mm to 10.5mm by gibraltar to fit my toms better, worked fine.
The air lift-section doesn't come _all_ the way up, at some point it's just a normal tom stand. But for the height I'm using my toms in, theres plenty of air lift-"zone" both lower and higher.
Something I was wondering before I got my hands on it:
You can remove the second tier from the base, and nothing explodes. The stand seems like it could survive in the hardware case, theres nothing fancy exposed.
I guess this would be kind of useless if you have memory locks on memory locks all over your kit. (Setup exactly the same every time...)
