been vaping the vertical micro coil in my pt2 for 2 weeks now. my only complaint is its not wicking fast enough for me but no gurgling or leaks im using cotton yarn for the wick. ive tried just cotton neither seems to wick fast enough. the only way i can get it to wick is to unscrew the top and watch for air bubbles to rise up through the juice and then its ready for 6-8 hits then i have to unscrew top again to get it to wick. ive tried less cotton, no change and more cotton just made it to hard to pull air through so i will have to keep playing with the setup till i get it to work by itself.
