I received my Ultra Max w/res and an atomizer interface yesterday that I got in a trade! Let me start by saying that this mod ROCKS!!! I am loving the hits you get with this PV. But thats also where I need help. I cannot get the res to wick the atty. I soaked the res, then dripped 4 drops into atty, and it hit good for about 15 good puffs(not constant puffs, I took breaks). I went as far as letting it sit for half hour without touching it. I removed the res and it was indeed wet. That was with a standard resistance 510 at 3.7. So today I popped in a fresh battery, and and loaded the clean res, and attached a new LR 510 at 3.7. Again I get 15 good puffs, then dry hits. Even if I let it sit for a while, still dry! I resorted to dripping 7 drops and getting my puffs, then another 7 when I get dry hits, and all this time the res is wet!!! I've even tried doing quick puffs without activating and nothing. Can someone please tell me whats going wrong here? Like I said I do love it though, so much I'm ordering the other body and battery sleeve tomorrow, just to have 2, one with res, one without. Thanks in advance for any insight and help!
