Customer Reviews


5 star rating  Just what I wanted
Michael from Frisco, TX USA
Some reviewers have noted that the 'blue' pointer seems a bit faint. It's actually a violet / near ultraviolet laser, and it will definitely light up things that fluoresce under long-wave UV.

4 star rating  Ok
Gary from USA
Ok for inexpensive laser's. Red and green were fine but blue was a little week.
