Magic fingers

I seem to have managed to revive my Nikon ML-L3 remote that died. I took it apart and, as expected, it's a single PCB with no obvious visible faults so I just reassembled, left the battery out for a day and when I tried it again in vain hope, it worked. Mysterious but not complaining. I was lucky this time in that a friend had a remote I could borrow but I wouldn't like it to crap out like that again when I'm in the middle of a shoot that needs it. Still, buying a backup remote seems a little extreme. Just have to deal with it if it happens, I guess.
