Nope, not by my standards anyway. I don't seem to have the problems others are, I haven't tried holding the guns yet, might look into that.
My issues with him are that he looks and feels cheap. He does have diecast feet, but that's all. Grimlock was certainly worth his price tag, IMO anyway, because of the detailing on the figure. Hot Rod has next to no detailing. TakTom would probably say the trailer is a factor, which it certainly would be, but even so.
He's still good and I'm happy I bought him, but he's far too expensive for what you get.
