It seems my brand new x105 looses power fairly rapidly...although I only tried duracall alkalines so far. I estimate I operated the laser for a total of 15-20 min, on and off probably 60-70 times, while trying it out. After that, the beam strength dropped considerably...appearing to be abot a 5mw strength. NOVA estimates a 2-3 hour life, which seems way off... Anyone else see this in the x105? or similar situations? Or could it have power issues? At first it performed perfectly (igniting caps and matches and such).... .....any help?
