I just built this G1 Optimus prime model, although it looks good in the picture it has a couple problems. All of the joints are either way too tight, or way too loose. The arms are a good example of this. If you know me from the anime stream, you'll know I mainly build Gundam models, and the occasional pokemon model if I can't find anything new. So I have PLENTY of experience with these. I'd say It's equivalent to a high grade in complexity. So it's good for beginners although there's better kits out there. I mainly got it because I had an itch to build something and couldn't find anything else new.
