A Kayfun is an excellent choice for a Provari. I'll respectfully disagree with the above comments about a Provari not being ideally suited for a Kayfun. They work like they were designed for each other. In fact, popular e-cig reviewer PBusardo's favorite setup is a Kayfun Lite Plus on his Provari's. Kayfun-style RBA's are probably the most popular rebuildable tank atomizers at this time.
The Kayfun is designed to perform best at 1.2 - 2.0 ohms, perfectly within a Provari's range. My builds for my Provari range from 1.2 ohm - 1.5 ohm. Going much lower in resistance could melt the Kayfun's insulator. A Kayfun was not designed to be a cloud chaser, it is best known as a flavor machine.
I've owned an authentic SvoeMesto Kayfun Lite Plus 2 for about 3 months now. It produces excellent flavor if not incredible vapor, but totally adequate for my needs. It is extremely easy to build on, easy to fill if you have a blunt needle/syringe (bottom screw fill hole). Holds approximately 4 ml of e-liquid.
My only complaint, if you call it one, is the airflow is on the tight side. Compared to the drilled out caps of my drip atomizers, its got a noticibly tighter draw, I'd really like to drill out the air hole, but I'm not about to try to drill out the thick stainless steel without access to a drill press and ruin a $100 tank with a broken drill bit stuck in the hole.
I notice that the EHPro clones have a couple of versions with a larger hole and dual air holes in an attempt to improve this issue.
