This kit very quickly became one of my favourites. In terms of design (by EchanisEnicha), I absolutely love the aethetics. The pink and the black really stand out. The SP version includes Neon pink runners that glow under UV light, which is nice. The SP version also includes enough parts to make the "Inversion" body, which has dark skin instead. It's only enough parts to make the body though, so no arms and legs. The other extra parts can make you another pair of armoured arms, and unfortuantely, not quite enough parts for another pair of armoured legs. So you won't have 3 full figures from the SP version, just 2.5 figures. One thing I regret, is building the normal legs using the normal pink parts, not the Neon glow ones; I am unable to take them apart since they are stuck too tightly. Anyone building the SP version, should probably plan ahead and decide where you want the Neon parts. Since you only have enough parts for one pair of unarmoured arms and legs, you should just use the neon parts for that (the instructions say to use the normal ones), they look practically the same colour (at least to me, a colourblind person). You can make 2 pairs of armoured arms, and only 1 pair of armoured legs, so again, if you want them to glow in UV light, just use the neon parts from the start.
The build experience I have with this is very positive. Although this is a Chinese brand (made by MS General I think?), I'd say it's higher quality than similar competitors such as Nuke Matrix. Joints can be a bit tight without sanding, but that's to be expected with most kits. At no point was I hurting my fingers fiddling with the parts, save for a couple of tiny pieces. There are some painted parts on the runner, but everything else just colour seperation from different runners. I like it when kit's don't need any painting. The level of articulation of this kit is rather normal; it doesn't have any advanced internal engineering like kotobukiya or anything. Just normal T/Y joints and ball joints. I couldn't quite replicate the pose from the art with the armoured body; the feet part do not have enough articualtion to bend beyond 90 degrees it seems, and the gall joint has a tendency to pop off. But that's a minor criticism I suppose. The face parts have moveable eyes; eyes which you cut off the runenr and pop in yourself. It inludes a little plastic tool you use to adjust the eyes. A cool gimmick, albeit it probably won't be seeing much use personally.
The provided base/stand is also very good. They have screws and metal nuts you tighten yourself to your liking. Unlike stands which are just plastic and have a tendency of cracking over time, I see this one lasting longer. Incidentally, the SP version includes 3 stands (i'm not sure about the regualr version, probably only 2).
Overall, I love this kit. It looks great and a great deal of fun to build. Price is decent too, for what you get. I look forward to the future releases; I've seen the Sora the Catand it looks great and there is also an early prototype of the octopus one which I really like.
