I have about 50 tanks but this is one of the best. Better than the griffin imho. Machining is perfect. Everything about this tank is big: size, build deck, airflow hole, wicking holes. This needs coils with at least 3mm id. If not it will leak because of the size of the wick holes. Flavor is great and clouds enormous. It has also one of the smoothest airflows of any of my tanks. The price is almost ridiculous. 7.99$ . If you like the griffin or gemini, don't buy one, get 2 or 3. You won't be dissapointed. This is a superb tank.
