This is undoubtedly a great kit from start to finish. As I was putting this together I only had experience in building 2 High Grade kits as I was watching Neon Genesis Evangelion for the 2nd time. The parts themselves are not that flimsy but because this is a 1/144 scale RG and compared to HG kits there is alot more parts and they are small but very well detailed. Once built you have something that is about an inch and a half taller than a regular Gundam HG that is an absolute spectacule to look at and pose. There is alot of accessories for this kit, 4 sets of hands, Pallet Rifle, Umbilical cord and two knives that can be stored in the shoulders whilst the other two hands are holding them. Unforuntely this is not the kit with the transport stand as its part of the DX kit and its more pricey. If you love Evangelion or love the design for the evas, this is a kit that will last you a good time to build but will look astonishing on the shelf.
The only 2 cons that I can think of is that some parts of the manual are vague, I wished it shown you more of the orientation of the parts because I assembled the spines on the inner torso the wrong way round on the first pass. Some parts like the triceps like to fall off and are hard to nip off thanks to the undergates which by the way need sanding off completely to require it to sit flush and the metal sole part of the left toe liked to keep popping off. So I hope you don't mind gluing some parts in place to get more of a cleaner finish.
Otherwise 9/10 kit, fun build and looks super cool. Take your time when building.
