I am very new to vaping, but I've never had a problem with my PT II Mini and only a little with my PT II. What I found, though, is that I lost the rubber o-ring on the base of the Mini without knowing it, and while it still worked, the draw was not right until I replaced it with one of the spares that come with the clearomizer in the box. After purchasing these spares, however, I realized that the spare o-rings in the box are for the drip-tip, and are too small to adequately replace the seals in the top and bottom of the tank assembly or for the clearomizer base. Huge difference! At 34 cents each from The Digital Cig, you will not find them cheaper anywhere (the only other vendor I found was charging a dollar a piece!) I have now already stocked up on both sizes. So I say, when in doubt, try new o-rings!
