O-like green laser pen

[simoneken1]

hey guys, i'm thinking about buying this Silver chrome green laser 50mW/good finish [OLSGL50] - $26.99 : Zen Cart!, The Art of E-commerce
but i have no clue what kind of batteries go in there, does anyone know?
also, is o-like safe to buy from with your credit card, i'm not really a guy that trusts that kinda stuff

Not positive, but it looks like 2x AAA. I would advise laserbtb however, they have consistent high ratings whereas o-like has mixed ratings: LP 515nm 532nm 1-150
