The Kayfun Prime is a pure “mouth-to-lung” atomizer. It inherits the functionality and design language of the Kayfun 5, but the inner life has been completely redesigned and tuned specifically for MTL vaping.
I've been purchasing SvoeMesto Kayfuns for years but after buying the Prime I treated myself to the Prime Special Edition along with the matching PEI tank. It's high quality from top to bottom. Threading is superior, no leaks and the famous Kayfun vape. The gold plated contacts I feel do help conduct the power to the coil. I'm happy I ordered it and I know it will last for years.
