First one arrived with a stripped thread on one post so it wouldn't tighten up. Vaping101 replaced that for me and second time round it's pretty good. Very small (which I like) so be prepared to fill more often than most. Plastic tank, so watch what you put in it. But it builds easily (deck is like a shortened version of the Zeus Mesh) and vapes well. Plenty of flavour and nice smooth airflow. The one huge letdown is the silly anti-leak flap over the fill port - you need to use a needle tip, big bottle droppers won't work without leaking, ironically. Even with a needle cap, it quite often leaks out of the vent on the opposite side, so filling it often results in juice everywhere.
With a glass tank and a usable fill port I would happily give it 5 stars but I'm already fed up of struggling when filling it so can't recommend it.
