Just got my Black one. took the tank apart and rinsed it off, primed the .5 OCC coil, pop'd it in and filled with juice. good flavor, no issues with leaks. Box mod feels good in hands, only gripe is the battery door doesn't "latch" like I'd like it too. But thats just OCD talking. So far I'd say its the best 60 bucks I've ever spent. Love my Provari mini, but this should yield longer battery life, has much more power, more options. We'll see how it does on the drop test, whenever that happens.
