I just got this guy the other day as a birthday present, and holy! This is my first Masterpiece experience, and I can tell that I will most likely stick with 3rd Party from now on for MPs. At least for the most part. Crackup is extremely well engineered, and is built to last. Nylon plastic is used in most of the problem areas that can easily bend for Transformation, and bloody hell he's full of diecast! Not only the feet and pieces of the chest, but also throughout his internals. Super happy with this guy.
Oh and TMan, I would recommend at least switching out the face to see how you like it. At first I thought the alt face looked mushy, but after switching it out I realized just how huge the chin was on the other one. His boxy, loose cannon, Stunticon head just doesn't suite a handsome Squidward face imo.
(If you want a pic before trying it, lemme know! I already have some good ones taken, lol)
I do have a couple small issues with my copy however. Firstly, the headlights are meant to both have clear plastic dripped into the indentions over the painted details, but one side lacks that. Not a huge deal since it took me over a day to notice. Also his spoiler section does fall off at times, but that can be fixed easily with a couple dabs of superglue. Overall, the issues are very minimal and don't influence the functionality in the least bit.
I am just hoping now that after these guys, maybe X-Transbots will finally give us that cartoon accurate G1 Devastator I and I'm sure many have wanted. I feel it's about time. The Constructicons have had enough artistic license and masked faces. Bonecrusher and Hook need mouths! And HasTak's unsturdy recent attempt at it just won't cut it.
P.S. You make great reviews, TMan! Glad to see you on Seibs too!
