    Awesome flavor

    Don't let the inverted coils throw you. It isn't that hard to build. The flavor is outstanding.

    Best RTA

    The airflow is nice and clear even with two coils at 3.5 mm diameter. I mix my juice at max VG +90% and I don't get dry hits. With the same flavor I get with my RDAs. The tank is a good size to keep me vaping awhile and let's you see right to the bottom. The slide up filling hole is nice because you can fill right to the opening and never over fill it, but I would have to say the best feature of all is that it does not leak, Ever. I've used every RTA under the tree and this is by far the best.

    Engine 2 OBS

    The OBS engine v2 has great flavor. It is not hard to build on despite having to build "upside down". I love the flavor I get from it and the design is aesthetically pleasing. The new drip tip feels great too. The only drawback is you can't build with larger more exotic coils. They just won't fit the build deck. Other than that it is a great flavor rta.
