I just got my Tornado Mega Cartomizers today. I love them! I don't have a syringe yet. I popped the 2 top pieces off and poked the film membrane with a paperclip, then I used my pointed drip bottle to add E Liquid into the bottom. (Saw this on a video.) Worked well for the first fill since I don't have the syringe yet. Kinda over filled it a little bit, but not bad at all, for my first time. Couldn't wait to try it out! LOL Anyway, I love the consistent throat hit and vapor! A LOT!!!! It's actually SHORTER than the cone shaped atomizer and cartridge I used before! Cool!
