Review: Works well - Seems to work great. Just a prelim test at 6 volts (minimum seems to be 2.2v to turn on) it burned my black mouse pad. I'm not a pro on this stuff but I've never had a 5mW laser able to burn things 12 inches away, but I'm happy with extra power but just be careful this is way more than a typical 5mW laser pointer, WEAR EYE PROTECTION I pointed it at something dark 30 feet away and had to peak over my glasses and it was pretty frickin' bright.
Review: These modules require a kick to turn on. - I purchased both this 450-nm module and the green 520-nm module at the same time, and they share a quirky trait. If I power them from my bench supply by connecting them first and then hitting the power enable switch on the supply, they both produce the faint broadband emission that other reviewers have described. At 3.7 volts they draw only about 4 mA. However, if I enable the power first and then connect the leads, they both lase immediately, drawing about 100 mA. My only explanation is that something in their drive circuitry doesn't like the soft start that the power enable switch on the power supply provides. They require an abrupt application of the voltage to function properly. I confirmed this by simply applying the leads to the terminals of a 3V lithium ion battery. They both lit up immediately. This could explain the inconsistent behavior reported in other reviews.

I set it up on a 6v system for an engineering project. It shines very bright and focuses well.
