4 atomizers on 3 different mods and none are vaping.Two avocado 24's, avocado 22 and kanger top tank.Have tried all different builds,wires and wicking nothing works.1 or 2 normal hits after build then nothing but hotair.Numbers are exactly where they should be every time yet it hits like there are hot spots . I've tried contact and spaced builds . I'm at a loss . Anyone ever heard of this.Insulators maybe? !?!
