Strong, round beam visible indoor in daylight. Easy to screw off two lenses in order to access the KT-crystal. Here is the beam very thin, and can burn plastic instantly.
May be not full 50 mW green. Infrared light also present in output due to lack of filtering. Bad soldering of wires (the fall off easy, but easy to solder back). The driver board gets hot after a few seconds, but doesn't decrease laser power.
Great module for your DIY-project, considering the price.
A cheap DPSS laser with good power and beam for this price.
