Hi Sam,
Well...hmm heres my experience getting green 50mw from Singapore. I do think paying (like I did before) 100 bucks at jaycar is a bit hexi just for the laser module, considering I payed 20 for mine. 5mw is a bit to weak for my liking.
Look 20 and the risk of losing it...do you go to the casino
Be sensible and you cant go wrong, whats the harm.
