Just bought a greenie, thanks. I had 2 5mW lasers from Amazon that I bought 2 years ago. The first 5mW laser I got from a company on amazon was called "HDE". The button eventually was too hard to press and got dirty from lint buildup (More careful now). The first laser was definitely overspec It was way brighter than my acclaimed 50mW O-like laser, and much much brighter than my 5mW Wicker lasers Core. 2nd was from a company called Sewell Direct Inc ( I don't think they sell lasers at all anymore on amazon)That one almost blew up in my pocket, I had batteries in the laser and it was in my pocket, I felt stinging against my leg, I noticed smoke coming from my pocket , and I went into the room and dropped my pants immediately. That was a scary experience for me. In case you're wondering How I remember all this, I just looked up the transactions.
