Hey All, I got a cheap GREEN LASER for 29.95 on Ebay from seller LASERPENS that will burst balloons and burn tape amazing light, its advertised as a 5 Mw but its adjustable up to 15Mw and its very bright for the money a real fun toy, no POT MOD necessary at the POT is fully adjustable no mod just put a small screwdriver in the adjustment HOLE and make it brighter by turning counter clockwise, It uses battery's faster but you can adjust it back again.. Lots of FUN..
