2015 new 445nm 3500mw blue laser pointer (Use Nichia NDB7A75 3.5W Laser diode)

I am very impressed with this laser. It is extremely well made and the beam is perfectly centered. The options of different batteries is a plus. I have several lasers and this one is definitely my favorite. I chose expedited shipping and it arrived very fast. This laser is worth every bit of the cost. Thank you Luck Laser.
