These stairs are easy to use with the staging (we're using them with the Thomann Tour Stage with 60cm legs). The only issue I can forsee is that the metal plates that slide into the staging are an essential part of the stair, and are quite small - hopefully they will not get lost easily.
To tighten the stairs and fix them to the stage, you need an 8mm hex key - this is a bit of a shame, as the rest of the stage can be assembled without the need for tools, but it's not too much of a hassle to do this.
Overall these are a really sturdy set of stairs that are much easier to install than the screw-together non-adjustable stairs.
