Of all the reviews I have read on the PA, EVERYONE who got it is pleased with it. This, and batteries can prove to be a bitch. I cant tell you how many batteries I have destroyed (or have destroyed themselves) by coming into contact with any sort of metal that causes them to discharge rapidly. (Keys, pocket change etc) Ive burned the fuck out of my pocket as well when this happens. PA is the way to go for this.
I have had my MFLB for a couple of years, and it still gets used on the regular. Simple, yet stupidly efficient (and a lifetime warranty)
