You know you're dealing with a dangerous toy when you see the words, "world's most powerful handheld laser." The Spyder II GX Laser ($1,700) is a military-grade handheld laser that's sort of a like a laser pointer, only much, much awesomer. Sporting a lightweight 6061-T6 aerospace aluminum shell and powered by a single 18650 high capacity lithium battery, the Spyder is airtight and water resistant, and is the first portable laser equipped with thermoelectric cooling, letting you use the thing for more than two minutes without it getting hand-burning hot. So what's it good for? If you have to ask, then you shouldn't be buying it, kid. As you'll see in our first-ever Uncrate video, this thing was designed for those of us who aspire to wreak havoc on the world.
