It's a very good laser. Very bright light and very cheap, so a perfect choose for me. All five lasers worked great without problems. It's not adventitious that the Average Customer Review is 5 star
short the wire but enough strong and I can solder with it without difficulty.
I tried it with 3V and I see a laserline with good contrast, when I control it through of the aquarium. The fishes was very surprised and curious :)
Supposedly the leserline (not just the red dot) be seen through of thickish smoke
