Author: Walter R – USA – March 2010 I was asked to provide feedback on this product soon after I purchased it in May 2010. I don't care for reviews that are based on a fairly short time period of usage. I prefer a longer duration of usage and a straight forward evaluation of the product in question. I purchased the Spartan 100mW green laser after significant research on the web exploring all the available options. I was very hesitant to spend this much money on a product without being able to experience it first hand.
I have used the green laser extensively for the last 5 months for numerous hunting trips, ATV trips (mates thought it was awesome on the 2 AM power line trail adventure, the culmination of a 85 mile day), fishing (and locating a friend's dropped car keys in about 6 feet of water), stargazing, on a family cruise ship vacation and for educational purposes with my two children. I have had no issues with the device and it has performed exceptionally well. It is amazing how bright this laser is. There is no question in your intended "target" when you are trying to communicate that information to another person right next to you or several miles away. From dusk to dawn, this laser is phenomenal. I am very pleased with this purchase and wouldn't hesitate to make it again based on my experiences thus far.
If there were any negatives at all in the transaction, it was a minor one - I was not fully aware that the necessary battery (rechargeable 18650 Li-ion) and charger was not included as part of the original package and upon receiving my laser, I had to make that purchase. This is a high quality unit with tremendous usage potential, the entertainment value alone is worth the purchase! I would not hesitate to recommend this product to friends and family who are in the market for a powerful laser pointing device.
