My original passthrough was dead on arrival. Steve was kind enough to replace it with a working one. But just after a week, it started acting up. Right now it is cutting off too soon and I am unable to get descent amount of vapor. I have treated it with great fragile. I tried draining it overnight to see if any liquid got inside, but not a single drop appeared. I am too shy to ask for another replacement and I would rather order a new one. My concern is, what if it dies out too soon again? =\ My 3 week old penstyle atomiser and one of my battery are rare breeds and puts out tons of vapor. The throat hit with that combination is amazing even with low nic liquid. Please share your experience with your PS USB Passthroughs....
