Ok I don't know if I'm jinxed or what but I love my new passthru, it was an auto and after a few days it died. Then the sent me another one and it has died also and now my only XL auto has died after a few weeks, these were my favorite two batteries and I am about to give up! It seems the sensory that starts the batteries have died. What am I doing wrong? Am I using them too much or too long? Should I go for manuals, when I had manuals before the button would get stuck and wouldn't work. Any suggestons?
