In my case this was the surrogate while I lived in an apartment that definitely wouldn't appreciate a full-sized pin. This was a project pin from ebay - cost more to ship it than I paid as a non working unit. Opened it up and reconnected the incorrectly installed shooter spring and its worked great since. I refurbed a good portion of the mechanics (sticking from dirty balls), but haven't worked on lighting it up yet (9v). Next is to touch up the pf paint. Very much more difficult with all the pins and plastic.
