I repair them and can tell you they are very well made. The lenses are all excelent quality. I'd say this camera was built to last forever with enough adjustment room in the mechanisms to take up the slack for more than a lifetime of heavy use. "Built like Russian tanks" is the saying and justly so.
As with any camera, handeling it with respect and never forcing it if for any reason if it jams is key. Jams are generally user error and repairs are a result of this in an effort it to overcome the jam. If it doesn't fire, stop and think before cranking harder on the lever. You forgot to take the dark slide out, revolving back may not be clicked in, your hand is leaning on the little silver tab oin th e side of the rev back, lens was put on wrong, but they don't drop dead for no reason at all aside from lonelyness. This camera want to be used but treated like a lady.
With prices so low, how can you not get one?
