Double check your memory... The bigger VN comes in the boxed set, but the Mini comes unboxed with just one head from GotVapes.
GV is definitely not selling knock-offs of anything from Vision. Chris (Badkolo) from GotVapes worked on the development of the Vivi Nova and the Stardust, and was even
given credit for it on the Vision website.
They are tight with Vision, GreenSound, as well as others, and now SmokTech. It's genuine stuff from them.
Disclosure stuffs: I work on GotVapes contests, and as a result am friends with Badkolo.
But, for what it's worth, I don't use their products for the most part. I have never cared for top-coils, even the VNs, which are apparently the best TCs to date. GotVapes focus has always been the top-coil stuff. I'm a fillered carto user (Boge and ST) in a DCT. I'm kinda enjoying the BC Phoenix XL 1.6ml, but haven't tried the 3ml Phoenix. I am really looking forward to trying the Phoenix Raven.
