I get small things from China, confirmation tests and cross cyls. I tend to lose them so I dont want to spend too much and have had no problem. The quality was fine and the lenses focimetered accurately. I recently bought an Ishihara test from India, again no problem, and I am currently waiting for a text book to arrive from India. Its the usual ebay thing check out the sellers feedback. Would I buy anything so expensive as a ret? not sure. With the small things if it goes wrong its not much of a loss. I’m not helping much am I??
