Until recently, I’d been using a Magneto mechanical mod for my coil builds. Various build problems aggravated me, and when it broke, I replaced it with a Stingray clone.
All of the contacts on the Stingray are copper, which enhances conductivity. I suspected this was a gimmick, but it does actually heat up more quickly.
The top cap has a floating firing pin, which allows any tank or dripper to sit flush. Here it is with a Patriot RDA. With a 0.9Ω coil, it generates massive clouds.
