I just received my replacement M-mount adapter from him today.
I am pretty sure this is from his first batch of revised M-mount adapters, because in the meantime I had ordered another adapter from him and he emailed to ask if he could delay that a couple of days until he could send the M-mount adapter as well. (I told him that would be fine.)
He had said that he would ship on Tuesday, March 3, so if that's accurate it took just over two weeks to arrive. Incidentally, it did not come to me directly from him; apparently he ships them to an associate in the US, who then sends them to US recipients. That person (in Milford, CT) shipped it to me via priority mail on March 16, so once the shipments reach the US, they seem to move quickly.
The service Khachadurian reports receiving from him is certainly less favorable than what I have been getting, so I think K. is very justified in demanding a refund. But I can say based on my own experience that this certainly isn't a scam; so far I have ordered two adapters and have received THREE adapters (including a replacement for the original out-of-spec one.) I suspect that the variable results people have been getting have more to do with the vagaries of small-volume contract manufacturing and international shipping.
I received the shipment at work, so haven't had a chance to try out either of the new adapters yet; will let y'all know when I get a chance to look them over.
PS -- If somebody just wants a sure-to-work M adapter with as little fuss as possible, I'd still suggest getting the RayQual/CameraQuest adapter; they have the best track record and the vendors (Dirk and Stephen) seem to be nearly 100% reliable. But I appreciate the work RJ has been doing trying to line up manufacture of a wide range of adapters, so I have been inclined to be tolerant about the problems he has encountered. Incidentally, in my most recent email from him (yesterday) he said he expects Nikon F adapters "will be complete in about 2~3 weeks..."
