My 1955 Rollei Automat is still working. It's flash sync doesn't always fire or fire in-sync, so I don't use it.
Quality control in China is slim to none. It's gotten better over the years. I'm sure the earlier ones are complete garbage. I'm sure there are several people who love their Seagull's. It's just hit and miss. I'd personally rather have a Rollei, a Zeiss Ikoflex, a Voigtlander Brilliant, a Minolta Autocord, a Mamiya, a Yashica Flex, or a Ciroflex. Basically anything besides a Lubitel.
