I've had my MVP 2 for a little over 3 months. For the last few days, it just hasn't been hitting right. It has a very tight draw and I have to vape for the whole 10 seconds just to get a somewhat decent hit. At first I thought it was my tank, so I tried swapping it out with all of my others (nautilus, iClear30, Vivi Nova, various Aspire BDC's) and all have the same effect. They all have new coils, too. I clean everything regularly and I also tried lifting up on the pin slightly, as suggested by a friend but it's still not hitting right. VERY frustrating. Any suggestions?
