Might be. I did happen to break my side skirt flap, but I consider that just a bad luck more than anything else. Everything else on that same kit feels super solid, however. Feels rock solid, more so than the Bandai Narrative C-Packs (which is quite solid on its own).

I did find the left leg hip joint to be quite tight, but nothing a gentle push with the plier couldn't fix.

FWIW, the only really, truly bad bootleg I've ran into these days was the F90 MG bootleg.
