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 more powerful. 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.
