Ricoh KR-5

I wanted to buy that, to have a simple camera, for using my Pentax-K mount lenses. Bad deal: the shock-absorber foam for the mirror felt in pieces (with bits everywhere on the mirror and focusing screen), the selftimer lever broke in my hand, and the lens unlocking key is no more there, it is necessary to push the small remaining metal piece with the nail. The shutter works from 1/8 to 1/500s, not much more than a simple Zenit, what use having a metal-curtain shutter ? In short, that is not worth the price I paid. Besides, once cleaned and changed the shock-absorber foam, it is supposed to make images...
The lenses are called Riconar, in french it sounds like "laugh, sucker!", may I find a relationship with the guy who bought that without watching everything?
