He is very cute and silly! The faces he has are very nice and the accessories are very well made and thought out!

I finally got my hands on Armin after they reissued these older nendoroids. It's interesting to see how the craftsmanship of these figures changed during the years. Armin, for example, has less number of joints in the arms and legs so you can't do much with the poses once you make them as they had instructed in the manual. There are three face plates but the one where he is injured is not interchangeable so you can't have that hair piece placed on another face. The swords don't really fit very good in his hands (the grip is too weak) so they easily fall out when you try to move the figure. Some parts were pretty hard to put together, while at the same they felt so fragile - you're not sure whether you should apply strength or not. Armin's nendo is the most delicate one I have in my collection so far - the first one I was worried I would break.
So, the machinery is not perfect, but the sculpt is very on point. The paint job is also very well done.
All in all, he is a good nendo and very sweet. :D
