Like most Zaku II ver 2 this one snaps together rather easy. If your having to apply alot of force you are likely putting the parts together backwards. The one sore spot are the energy pipes. The beads are hard to move off their runner(k) so take your time or your fingers will hurt. Due to the color (light salmon) nub marks are difficult to work with on the armor. The hands out of the box are only partially articulate in that the lower three fingers are partially fused. You can cut these apart to increase articulation but it does impact holding its weapons.
The inner frame is well detailed out of the box. Painting the inner frame will take a long amount of time details to be done.
The jointing system on this unit are strong but easy to move. It will even hold a vertical kick pose.
The only extra parts with this kit are one helmet and depending on which helmet used 1 or 2 antennas
