200mW 405nm Adjust Focus Blue-violet Laser Pointer Pen with 18650 Battery

The Laser works perfectly. It is less-than 200mW as indicated on the Warning Label (maybe 50-75mW). I like the ability to vary the focus of the beam. Works well with fluorescent minerals. The battery provided was defective. However, Laserpointerpro remedied the problem quickly. Thank you for excellent service.

my battery arrived dead. however, everything else seems to be in order. also not to sure about the output being 200mw but it does burn electrical tape.

GOOD
