I've used Quick-Sticks forever and they're fine where applicable, as in non-tight fitting tires, which is what this tool was designed for, well before tubeless tires were even a thing. As kcjc notes, they're excellent for swiftly spinning around the bead once it's broken. They will break a bead if the tire isn't too tight, otherwise a lever of some sort would work better in those cases. I don't buy tight fitting tires and sure as h-e-double-toothpicks I don't run tubeless, which would be an exercise in futility for myself.
