Author: Michael E – USA – Feb 2011 I have always been interested in lasers; particularly green lasers because of the ability to see the entire beam. I bought a 5mW green laser about seven years ago and finally decided to upgrade to the 150mW Spartan and all I can say is WOW! The laser feels very well built with a good hefty weight from it's all metal construction. The click on/off tail switch is nice and the laser is practically an infinite light saber. It is insanely bright! The entire beam is highly visible at night and even inside durning the day. If you're an astronomer looking for a tool to point out different constellations or simply someone that likes cool gadgets then this laser is for you. You can also play with it by lighting matches, popping balloons or whatever else. I would highly recommend buying the safety glasses if you're planning on looking at the laser point up close to protect your vision from the intensely bright light. Customer service through Dragon Lasers is top notch and has always been quick to respond (as quick as they can be being on the other side of the world) and very helpful. I will be sure to return for any future laser purchases. You won't be disappointed!
