Like that it uses aaa batteries - LaserMax Spartan Adjustable Fit LED Weapon Lights

This little package is GREAT! And the fact that it uses 1 AAA battery makes it so convenient and fairly cheap to use. I like the power the CR123 batteries and the like put out, but its expensive and sometimes tough to find those batteries. AA's and AAA's I can find at any convenience store and the name brand batteries have a 10 year shelflife. As far as I am concerned, that puts this light / laser combo my 1st choice. I like the easy to activate paddle buttons and the ability to choose the combo i need with a few taps of the paddles. I am giving it 4 stars because of the light it puts out. It has an almost a light Christmas green tint to it. Weird but i can live with it.
