Love the flavour kayfun 4 produce but ohm unstable with old silver spring. If you get the one with gold spring then it's stable ohm. The juice/liquid control threading will wear off over time. After using it for 9 month, my juice/liquid control part wear off and got replacement from SvoeMesto.
The juice in the tank stay clear compare with kayfun lite plus, juice become darker after vaping.
Easy to coil & wick. Super easy to fill. Can check your coil or recoil or rewick without loosing your juice.
Love it and it's perfect pair with ProVari 3.

Sure can. Actually it can pair with any mod but somehow the ProVari give you a smoother vape.
