    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.

    Upon un-packaging I noticed that the all brass construction of the laser head was well milled and bright. It was a pleasant surprise to see that since that means that I can solder plates, tubes, mounting arms etc to them without difficulty. I then hooked up two 1.5V button batteries and tried it out. All five lasers worked great, the point was still ... Read more
