Not me. Never seen a Cheung, nor his adapter.

I assume here you mean "non-OEM"

I think I have the same adapter from the same seller. It seems to work
very nicely with all the Zuikos I tried and the Kirons. Fits the Tamron
Adaptalls a little tighter, but fine. Fits about half the Tokinas very
nicely and won't go on some others, at least without forcing, which I
didn't try. :-) The obviously hand made, un-plated brass one that I
bought early on, and had to modify slightly, fits the few Tokinas that
don't fit in the newer, nicer looking one.
Remember, the third party lenses are reverse engineered from Zuikos,
just as the adapters are, so subtle errors can compound. Kiron seems to
have done the best job; they feel just like the Zuikos.
I agree I'd just go for one of the $20+ Chinese adapters again.
