Waterproof Green Laser Flashlight from Rayfoss

Подробнее о видео

Here is a mini-overview of the 50mW waterproof green laser from Rayfoss. Rayfoss Sells these in red, green, and violet, and in powers from 10mW to 200mW. The flashlight case itself comes in black, gray, and chrome. When ordering this laser, don't use the checkout system on their site (rayfoss.com), just email them your order and you will save a lot of time and hassle.

Here is my text review:

Just a note, do NOT put in the battery backwards, the reverse polarity will fry this laser in an instant.
