Have you been in a situation where you are trying to squeeze your release aid and it simply won't fire? You are squezing and squeezing and it simply doesn't move! So you make it more sensitive and BAM! Problem solved......for about 3 shots. Then its stuck again. So you back it off some more, worked last time, and again, it won't fire.
What's going on??
