wickedlasers--Core Laser 5mW, $30

What can you expect from a laser pointer from the home of the world's most powerful FDA certified laser?

    A better laser beam. Standard laser pointers fade after a few minutes. Never worry about losing their attention with the CORE™'s negative-feedback sensor system. You get the same stunning beam from the second you turn it on to the last second of battery power.

    More power. Big box store lasers give you small-package power. This laser gives you 2 to 5 times the power of standard laser pointers. More power means a brighter, clearer beam to get more attention exactly where you want it. The CORE™ is the brightest 5mW laser you can buy.

    Pocket full of power. It's pen-sized so you can grab the attention of the entire room with a captivating green laser light.
