The Caliburn G2 coil heads are notorious for being messy. While I have had the occasional messy pod, they do stay clean for the most part. The Caliburn GK2 uses the same pods and coil heads from the Caliburn G2.
The Uwell Caliburn GK2 device itself is pretty rad, it’s much less slender than the other Caliburn AK2 ( Koko ) but still offers a nice hand-feel, and is honestly so lightweight, that you could easily rock it on a lanyard.
At the end of the day, these KOKO Prime got me back using the Caliburn G batteries a lot more. I like the KOKO don’t get me wrong, but it is much more of a “lanyard” vape.
Form factor is much more suited to that. The Caliburn G is a much more normal natural shape we are used to. It works for a reason. Exact same vape, different form factors.
I did have some auto switch issues on the blue unit I received. That blue unit was from VERY early on, pre release. Every KOKO Prime afterward has been basically flawless. If I had to choose between the two, I would certainly go with the original Caliburn G battery / pod – 0.8ohm mesh coil boosh done love it.
