I have both the Dicswasher and the Milty. To test the unit put the little cap back on the nozzle and find a copper water pipe. put the nozzle very close in a darkened room and pull the trigger. You should see a spark from the gun to the water pipe. If your manly, put the gun on your arm and pull the trigger. you should get zapped! Also, pull the trigger slowly, if you hear clicking you are pulling the trigger too fast.
Do not point the gun at any electronics that may have sensitive electronic chips as the static charge could blow the chip!
