For me it's been my Zorki 4K and my Flexaret. Both survived being thrown out of the window of a moving vehicle into a ditch. Both cameras were in a camera bag in my truck and were stolen one night when I forgot to lock the doors. Apparently when the thieves discovered what was inside the bag wasn't, they threw them out the window at the end of the drive. I had Bill at Pro Camera readjust the rangefinder on the Zorki, and with the exception of a small dent on the Flexaret both cameras work just fine.
