I just started mine yesterday and noticed a lack of vapor on the 16 menthol and 11 pipe. I also have a wheezing sound from the battery / cart area so I am waiting for the other battery to charge and see how the two compare.
Right now I am chalking this up to inexperience and experimenting. Most of the posters here mention to give it some time.
Did you get the auto batteries? Those more so then the manuals have a learning curve as to draw. Try a quick primer puff followed by long....slow....easy draws. You will be amazed at how much flavor and vapor you get doing that.
Also, with the autos I tended to hold the ecig like a joint, with my thumb and index finger, covering up the seam to block some of the air. That makes a tighter, harder draw which I prefer. Gazoo suggested cutting the end off one of the condom covers and sliding it so that it partially covers the seam. You have to move it until it has the draw you want, it can only be partially covered or you will get no hit at all.
If you have the manual batteries, a slow easy draw is also helpful but not quite as important as with the autos. With either type the long slow drag is going to get you more vapor, more flavor and more throat hit.
Stick with it - you will get it!
