Well for those who are apposed to Proprietary Threading, that has now become a mute point as I have been vaping a Dual Coil Mega XXL Smoktech Carto on my Go Go Pro all day long and it is hitting like a truck with the new Go Go Battery to 510 Cartomizer/Atty adapter I got in the mail today. Granted I prefer the Go Carts myself but if you want longevity and higher voltage out of the gate and you insist on a 510 carto or atty then tis is the Device you want for sure if you are not into paying hundreds for a Mod
