For impulse purchase, I say these two are pretty good
The transformation is solid. the paint job is decent. It's only too bad that I won't be getting aerial bots for superion- but I might get either the harrier or F4 mold.
The only issue I have is with megatronus.
For some reasons the pinned hip joints are always loose in the sideway movements with larger figure. Even 86 Optimus prime is like this too. And the tank mode the chassis just way too thin, probably a budget thing. I think with the way it is designed and third party should be able to make a decent tank by adding more thickness.
Anyway, I don't know why but when I play with both figures there were a bunch of loose tiny plastic chunks and pieces falling all over the place. And look closely it's like a 90% of the pinned holes still have the leftover pieces attached covering the hole. Are they really in that of a rush to get these out that they cannot even drill and punch the pins properly?
