Question about CHMS Paradon Medic and Chromia

Hello All! i have a question. i was looking around for Animated Arcee figures to make customs out of (Chromia and Paradon medic, TBS) and my friend referred to a bootleg company called CHMS who made the figures i wanted. and i found one person selling Chromia for $30 and Paradon Medic for $40. and i was wondering if they were good quality, i mean like if it's just gonna fall apart like a bad Knockoff, or be wonderful like a good knockoff (like the over sized DOTM Megatron). I'm still most likely gonna purchase them either way, i just wanna know if i have to be careful. since i do wanna use these in a stop motion series I'm working on.
Thanks!
