Hello Everyone, my first post here. Three years ago, I won a small red laser key chain, a very cheap kind that you get at the vending machine at an arcade. At first it was interesting I played with it for awhile and put it away. And then just a month ago I came across that same laser and gosh it still works and used it to play around with my cat, she wasn't amused, but I sure caught the bug big time. With my old red laser I added to my collection, a green 5mW, an violet 5mW. Going to the deep end, I bought a 200mW green (so says the seller at Amazon), a 350mW red from a guy in Turkey. Like I said, a bad case of Laseritis, and more lasers to come from sellers on this board. I'm looking forward to talking to your guys.
