Interesting, as a few months a go I was interested in trying a pure top airflow tank, but at that time there was only two, I forgot the other brand, one was the OBS, both were only dual coil, which I don't need or want. This single coil version might be what I'd like to try. A lot of RDA's I own are top airflow, can't say they are better for flavor, but many reviewers and users claim this design is good for flavor, but even if they are equal, my MAIN interest was the holly grail of finding a LEAK PROOF tank, there are many pre-built coil type tanks like the Cubis, that I have tried, that while leak proof, never offer as good a vape as a tank where you build your own coils, besides saving you money you can use whatever coil material and resistance you prefer.
