Apparently slingshots are really cool now and nobody told me

I had a really nice slingshot as a kid. Not a Y-shaped stick with a rubber band on it, but a seriously legit metal slingshot with an arm brace and everything. But it had nothing on the Assolar SS-12, which I just saw on The Gadgeteer.
Look at this thing!Officially listed on Amazon as the "Assolar SS-12 Multi-function Super Power Stainless Hunting Laser Slingshot, Hunting Bow with Adjustable Spring and Quality Rubber Bands," this slingshot has a spring mechanism to amp up the power of your shots,
