I got DNA DK-73 in the other day, only put some parts on my 86 Devestator, while I got some 3D printed parts in a little while ago for him, I'm mixing and matching between the two, for example, the parts that attached to Dev's arms, I don't like the DNA ones because its doesn't suit the general look because its like falling off a cliff or rather the shape of the letter L, the drills are pretty cool looking, the only part I got a issue with, is for Scrapper, I need to sand it down a bit so that Scrappers legs can close together normally as it doesn't want to close properly with the part in, thou the main reason I bought the kit was for the hands, the other kits for the Constructicons have been uninteresting and made the worse part of him, his back, look even worse, so I never bothered with the kits until this one appeared on my radar, sure there's alterative heads in the kit but they are of Prowl, not Devi, so I not put them on!
