Well, i have made many times test of lasers before i came across 5mW apc green laser pointer. this is very special Class IIIa laser, while its projecting output power always keeps stable as 5mW in all application fields.
For formal laser fun and laser entertainment, it is not the correct choice. However, whenever it is used in high tech applied fields, such as lab experiment, scientific research or presentation for military targeting, 5mW APC green laser pointer has just made great work.
