Pros:
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
Cons:
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
Other:
Great for hobbyist and those who just need a small red laser. 3v DC. Great for light shows, nerdy things, toy guns...
Bottomline:
I'm going to maybe buy about $50 worth just for a neat display.
