But hold on they are in the side of the tube I missed them the first time I looked at it. And something that did thats really cool. Is inside the positive tube where the air flow should be it kind of splits around a bulb like stopper thing. To try to cut down on flooding can you take some pics. Of the bottom of the atty from straight down the positive tube as well as above the 510 threads if all else fails take a small drill bit all the way through both posts. But I will warn you the 510 side wall is super thin and if dropped it will break off at the top of the last thread. Ive broken two of them. Yes I like the way they work but like everything they have flaws. The walls on the 510 connection could be thicker. Air holes could be larger. Air tube could be repositioned so that juice does not get into the path way and flood it out. The oring on the drip tip could be a bit thicker. I cant count the times ive been using it and the drip tip just slides out leaving it in my mouth. But how many drippers can you vape over 100 puffs ane and not have to drip. And it looks good on a ego. But also rebuilds can be a pita. I would do a video review on it but I dont have a working one. I'll buy a version 2 if it ever comes out but not the original but it is still a good beginner's atty.
