as expected
One thread in z-axis profile was missing(see photo). Some additional tools required to assemble(see photo). There was no bearing for z-axis at the bottom(expected, according to product images). VERY generous hardware. Everything is at required amount +1 more, that saved me two times, when wrong bolts was in the bag. But because there was spare ones, everything went smoothly.
Accidentally added wrong image about missing thread. This is correct image.
