Works well but poor instructions
I have used this for a bunch of knockouts in steel enclosures and it works well. My only complaint is the instructions are not great, and I managed to mess up the assembly a few times. If it feels like it is harder to pump than it should be double check you set it up correctly.

Works well.
Worked well. Had to punch wiring holes into steel studs, some .1” thick. Uni-bits are pore choice. Machined an adapter for the 2” punch to use the 7/16 pull stud. That is all that is need to punch 26-gauge steel. I needed ≈900 holes in my steel eve soffit for vents. Just hand Punch a .5” hole for the stud than the knockout punch, No drilling required. The hose could be a little longer.

Worked flawlessly, but
This must be metric, because the 2" hole is actually 60mm, or 2-3/8". So the biggest hole is not 2". It messed me up a little because I cut the hole thinking it was exactly 2", before measuring it.

It's super low quality
It just worked for 4 3" holes in an electrical panel, then the the hose started leaking.
