Everything went together without any fuss, just spot on. The pictures on the supplied 'manual' are tiny and hard to read, but as you take bits off of the tub, its obvious where everything goes on the chassis.
The screw holes in the bottom deck are countersunk just a fraction more the regular Cyclone and S tub, so the screws shouldn't go silver when scratched. Nice touch.
Mine's built with all 3 stiffeners in place, but its still flexible. More than the black/Hara Cyclone, but a lot less than the tub.
