Indeed not!
Just looking again at the design of the copies you can see why they are difficult to fit:
The lugs that are marked as 24mm from tip to base are only actually thin at the very base, maybe 6mm or so.
Almost all of that has those triangular buttresses and above that it's thicker and quite rigid.
So almost all the flexing takes place at the 2mm or 3mm thin area at the top of the buttresses. Which is why that is showing stress marks on the ones I removed. 
The OEM design is the same (thin) thickness from base up to the "wedge" at the top. The wedge is also shallower.
So they have a whole 15mm or so to flex and less distance to bend as well.
I also suspect the OEM material is more resilient.
All of which says that the Chinese ones have almost been designed to fit badly and break quickly.
