Great product and service... quick delivery

—— Fred Schmidt

This is the first company on all of this website that so far as I can tell does not lie about their products. Getting sick of companies claiming they have 10000, 30000 and even 50000 mw handheld lasers.

EC 60825-1 Laser Class Classification

According to the wavelength and maximum output laser power of laser products, laser products are divided into the following 7 grades: 1, 1M, 2, 2M, 3R, 3B, and 4. Among them, the two levels of 1M and 2M represent that the safety level of the product is the same as level 1 and level 2, but when using optical equipment such as telescopes, the degree of hazard may be amplified to exceed level 1 and level 2. Level 3 is also divided into two sub-levels, 3R and 3B.
