@6steelstrings that's awesome to know, thank you. I've bought and sold many tanks ever since I went back to vaping back in September and I must say the best ones I've used so far are the Serpent Mini 25 and the Merlin Mini RTA.
I recently bought the GeekVape Ammit, which according to many experts is one of the best in terms of flavor in 2016 but I am cannot for the life of me wick it properly and I end up with either a mutated flavor or dry hits, so I'm quite disappointed in it.
I'll be buying the OBS Engine today or tomorrow, I'm just waiting for a friend to tell me if he'll be able to provide the black version or if I should just go for the gold one. Is wicking this tank easy? I've had problems properly wicking the Aromamizer Supreme RDTA and the GeekVape Ammit tanks so far, while every other RTA and RBA tank I've used was and still is working fine.
I'm also surprised that the OBS is supposed to provide amazing flavor while it is a dual-coil tank, because from my experience I always got the best flavor out of single coil builds. As for filling the juice, I'm always careful doing it even with easy-to-fill tanks like the Serpent and the Ammit, and I never really fill it all the way anyways. I'm just glad I'm finally getting a large capacity tank for a change.
