>>7483440The KO Dios I got (shown here
>>7472068 ) seemed really nice, imo. The plastic didn't seem cheap, and I've collected KOs for years so I know what cheap plastic is like. It seems on par with Hasbro toys. The plastic is definitely shinier than 52Toys products, without that matte treatment. The joints are actually more firm than on my legit Dios, especially the tails.
They aren't without their drawbacks, by any means. On mine, the caps on the back of their heads likes to come off, as well as the heel pieces if you're not careful (pic related). Easily solved with a tiny amount of glue. They also did have the sharp nubs that have been mentioned before, but these came off easily.
The lobes at the base of the arms, I may not do anything about, since they make it easier for my hammy hands to get the arms deployed. On the other hand, the limited range of motion might start to bug me, so we'll see.
All of this is to say that the KOs can easily be made to be as good as any toy you'd buy off the shelf in the US. I would say that, for the price, they'd be great for repainting or customizing or army-building (or all three).
