I found a 91% on christmas day on line from a place called vapnificent for my dad. We ordered it and it showed up to my house the following saturday. They are showing them in stock still today. When it came in, the box had been opened, but everything was there. I have seen some pics of the kit out the box, and they show them coming with spare insulators, but the one we received didnt. The one I bought a few months back didnt either.... So I have no idea if they took them out, or if the seal sticker just didnt stick well to the box. Either way, they shipped fast, I got it built him a micro coil , and a few spares then mailed it off to him. he is satisfied with it, and wanted one after vaping christmas day using my russian RBAs.
they are out there. and the factory has a notation on their website that states the lowest sale price allowed is $92.50 Now that the holidays are over, inventories should start to replenish.
I have yet to use a Kaifun, or a Kaifun lite.... But with two Russian RBAs , a Russian 91% and now another 91% I built for my father, not a single one of them has had any sort of flaw or problem. It doesnt matter which name you get.... just get one.
