So its definitely solid built, almost impossible to make leaking but the flavour? Not the best. It actually ruins some flavours altogether which is the very fist time any tank does this for any of my juices. It does deliver on many occasions but half of the time the flavour is off compared to other tanks. I build it with medium complex or single wire coils. SS or kathal like I always do. For the price it lacks flavour. But it's still a very personalised properly built tank. I want to give it a 3/5 because of the price, but not factoring the price I would say 4/5.
