I'm in the same boat man. I have purchased my collection from Totally Wicked. I have 2 Tornado batteries, 1 mega Tornado battery and 5 Titan batteries. I gave up on the tanks because of leakage and lack of flavor, I've tried clearomizers/Smokymizers, and smoktech dual coil carto's. The clearomizers kept cracking and leaking and just tasted bad all around. The dual coil carto's were great on the initial fill but any refills afterwards they failed to perform. I just purchased 15 smokymizers and the first was a dud, the second constantly taste burnt and I cant seem to manage the tiny little plug without dropping or losing it. I haven't smoked in almost 3 months but I am out of idea's. I wanted to stick with things that would fit a 510 connection because I have so many 510 batteries but I am frustrated with everything I have tried. I don't mind spending the money on an entirely new device, but I have no idea what will meet my needs. All I know is that I haven't smoked in nearly 3 months but I am not spending any more money on Clearomizers, smokymizers, nor dual coils even though I have had the best luck with the dual coils. I am a heavy vaper and I like to chain vape. I dont care what it cost but I have got to find something that works for me soon or I'll probably end up smoking again. If I have to pay top dollar for a hi-end device, fine. I just want a reliable, consistent device that doesn't leave me frustrated and aggravated with all the maintenance, upkeep, and leakage. I don't wanna bother with syringes nor the tiny little plug on the smokymizers. Somebody please suggest to me a device that I can chainvape on with minimal leakage and minimal upkeep and preferably no syringe needed.
