Coppervape squonk mods, they fire relatively quick. You push the button to depress the fire arm to touch the battery, you get firing. They run about $20 US Dollars on Fast Tech for the aluminum ones. Trouble i keep having is they're made from soft aluminum, ergo drop them on hard surfaces and they malform. Then, you need to fidget with them a bit to get them firing. I don't have access to a computer aided metal or machining shop, else I'd just reform them back to "shape".
Maybe someone will get smart and make them from heavy duty "aircraft" aluminum like Mag flashlights are made from. Of course, I would then expect the price to at least triple on the "cheap" aluminum ones. So instead of $20 they'd be $60, I'd be hard pressed ... likely debate for weeks over spending that on one, but likely would. I mean shit, they're a good mod, just need to be made more durable.
No, I won't quit being clumsy. I'm a big old grubby country boy, clumsy is part of that nature. Besides, I'm always seeming to be around hard surfaces which deform crappy soft aluminum. Makes more sense to raise the cost and build a better product. I'm fairly sure I'm not the only one what would pay extra for a Coppervape built to tank standards. Design wise they're fine. They just need "tougher" grade aluminum blanks used. "Aircraft" aluminum is pretty tough stuff, go try getting thumped by a Mag flashlight once, see if your skull dents it or it dents your skull.
Oddly enough, the bras version of a Coppervape does not malform when dropped. (Yes, I know famous last words. I'll touch wood thrice.)
