You guys and girls that vape with metallic / aluminium drip tips. Do you get a Gentile Tingling like putting your tongue on the two terminals of PM9 battery. I find it get it. Even if my lips touch the top of the RTA where the drip tip fits in but only get it on a few mods.
I remember walking bare foot and standing on the extension lead the insulation was cracked on very clearly. No Earth Leakage in those days either. LOL.
