    Very very very cheap. solid red dot.

    The cheapest laser I could get were about $4.50 and were crap compaired to these.

    Wires are soldered on. runs on 3vDC. very simple. no extra driver needed


    beam does expand over relative short distances, but if you need to do the... buy something nicer.

    Might be a little tough to solder new wires on. Very small board


    Great for hobbyist and those who just need a small red laser. 3v DC. Great for light shows, nerdy things, toy guns...


    I'm going to maybe buy about $50 worth just for a neat display.
