I got one of these lasers off ebay and I'm sending it back! They gave me a really hard time to even take it back and want to send me another one but once they get it i'm gonna demand a refund!!! It's a piece of JUNK!!! The optical quality and out put is weaker than a cheap IR flashlight! I don't think this thing is even a real laser! it's looks impressive but looking at it with night vision it doesn't even put out a 10th of the light as compared to my 500mw IR laser! YOU GET WHAT YOU PAY FOR PEOPLE!!!
