Stands do the job and feel stable for 4-5 inch monitors, the Z design looks cool on a table. The K&M logo stickers are slightly rotated on the stands, something I've noticed on other K&M products I own, I guess German engineering can't solve everything.
K&M packaging is bad as the stands have to much space to move and bounce inside (no extra padding, just the 6kg of metal against the cardboard of the box), which means on some small areas the metal is scuffed from bouncing during transport. This also meant 3 of the 4 sets of rubber feet/pads must have escaped from the box through a hole made my said bouncing. I had extra feet laying around so it's a non issue, but all in all, the worst packaging I've come across lately.
