I was quite impressed with KO MP-10 too from an aesthetics and detailing point of view until I tried to transform him. I've never gone all the way because his legs are so stiff I worry about them breaking or remaining stuck.
I knew up front he was a fake but I liked his detailing so much I couldn't resist getting him (and I only paid RMB400) for the novelty value. Side by side with my real MP-10's he always makes for quite a conversation piece. He's the only fake I've ever had the desire to acquire... I'm a sucker for G1 Optimus...
The centre screw is one of the things that always suckers non-TF knowing people into thinking the real MP-10 is fake... so funny that such a little detail can be so telling.
