I know this
thread is a little old. I wanted to add something.. I don't know if it's just my particular vulcan or all of the did clones.. I can't understand why they go to all the trouble of engineering this thing only to have the air hole line up on the opposite side of where it's supposed to go. I know I can turn the top cap to line the hole with the wick but this makes the top cap looser instead of tightened down. My PV has fallen over a few times and each time the top cap goes flying and sometimes it messes up the exposed wick and coil.
Forget about taking it out anywhere.. with the top cap half unscrewed, it's too unstable for any use other than my recliner. I'm using cotton instead of SS mesh and the flavor and vapor are outstanding so this is why I put up with the negatives. I guess for $20 it's a good value as a recliner
vape here at home. It just seems that they could have thought to put the air hole in a better place. All in all, I don't regret my purchase. It's been fun playing with it and the flavor is terrrific (with cotton IMO)
