hey reckless. please go get yourself a tube of oxgard from home depot. just take your switch apart and put a little dab of oxgard on the two metal contacts where the metal ring on the button hits and it'll hit everytime. just make sure that you clean everything up and re-do it every two weeks. also, if you want an extra boost in performance, take the adapter off and put some on the contact there as well. this simple tip will transform your prodigy v2 into a beastly machine. i should make a youtube video on how to do this because it helps soooooo much. but im a little camera shy. hopefully someone will see what i've wrote and make a video. we can only hope... anyways, hope this helps. well, i know it'll help. c ya.
