This was an interesting build. It feels a lot like a bigger, more solid HG IBO kit. I mean, you can pick it up and shake it like a blocked up salt shaker and it won't budge. The articulation is pretty good too. The elbows rotate more than 90 degrees, it's knees allow it to kick it's own rear waist armor, and it can almost do the splits without using the drop-down joint in the waist. The shoulder armor does limit the arms upward rotation out to the side, but they still make it more than 90 degrees before it interferes.
There isn't really much to dislike about the quality of the build. My biggest gripes, however, are the lack of head movement, and the lack of extra stuff.
The neck is a stationary ball joint, which would be fine except that the underside of the head has a large sort of box that slots almost perfectly into the chest, so there is literally zero side to side movement of the head. Or tilting side to side for that matter. The head can be pulled upwards, however, to allow some up and down rotation.
The lack of any real extras is also a bit of a downside. The only options you have are open or closed hands. The weapon you get with it is really nice, with a detachable magazine and underbarrel grenade launcher (at least I think that's what it is), but again, that's all you get.
You also a very small sticker sheet with it for the eye camera. I haven't seen the anime that the Jo Hound comes from yet, but my understanding is that there is a war happening in it. You kind of need insignias or symbols with which to identify combatants so you don't shoot your own guys, right?
In all, I think this a rather nice kit with an interesting design, great articulation and solid build quality. I'm definitely going to have a look at some of the other kits from this series.
