Mine works fantastic, and it's one of the few cameras I own that I haven't had to work on. A Russian friend figured out that I'm always interested in buying gear, got in contact with another friend, and fifteen minutes later I was in a parking lot, forking over a few hundred rubles for it and a Helios 44. The body I don't use much, as I have better stuff to use screwmount lenses on. However, they're very simple, robust cameras with viewfinders that leave something to be desired, but overall get the job done. Every piece of problematic FSU gear I've worked on wasn't inop due to 'poor quality,' but simply from being old and never serviced. Next to a broken Zorki and Kiev on my shelf are two non-working Leicas...
