Got mine in a Co Op, and for 45 bucks, it is stupid to complain. All aluminum construction, lightweight and the replacement tank is glass. As a first time hybrid user, I have nothing to compare it to. I widened the air hole using a thin screwdriver, and I wrapped some kanthal around a pre oxidized mesh wick. I used too many wraps, so my ohms are way high to kick out some big clouds, but it seems to work. Scratches easily, since it is soft aluminum, but for a cheap price, I have a hybrid to experiment with. I would say it is a great novice piece. Nice kit, and worth it for sure. The top cap and drip tip are looser then I would prefer them to be, but meh... You get what you pay for.
Wrap some dental floss under the o-ring and that should tighten the top cap up.
