there is this 100mw red laser on Laserlands.com for only 14$! Seems to cheap to be true... anyone had any experience with it or laserlands?

You actually bought it from laserlands and it's the exact same laser?I've had that laser, it does indeed hit 100mW. You need VERY good batteries to get 100mW out. Average cells will produce 65-85mW output. The driver in this is very inexpensive and uses the cell voltage as a voltage reference, so the diode only gets full current when the cells provide exactly the right voltage.
