Finally opened mine, and he's good. No paint issues or anything on mine. Definitely a major improvement on the Universe version. The shoulders on mine are a little loose, but other than that everything locks into place nicely. Transformation is pretty decent - not too simple, not too complex. I'm glad I got him, but couldn't help but feel a little bit like "Is that all?" after reading some of the gushing praise he's been getting on teh interwebz...which is entirely my fault for getting my expectations too high.I was expecting something that would blow me away like, say, RiD Scourge, but what I ended up with was exactly what was TakTom was going for - a really solid, decently-sized, nicely-detailed, well-designed representation of G1 Prowl, no more, no less. He's been overhyped quite a bit IMO, but regardless of that he is a nice piece that's well worth picking up. Just be aware that that's all you're getting - a really good G1-style Prowl, very much the definitive Prowl but nothing more - and you won't be disappointed.
I voted 'Only if', as in only if 1: you can find him for a decent price (I got mine for $45-$50, but much more than $60-odd, $70 tops I think would be pushing it in terms of value for money) and/or 2: you're a fan of the character (which I sort of am).
