So for my 1 month without an analog i decided to upgrade my gear. I had a basic ego twist/pro tank mini setup and wanted something just a little better. I ended up getting a vv/vw Tesla and absolutely love it. I had intended to get a Kanger Aerotank with it but the b&m i was at didn't have them. I wanted to stick with kanger since my wife has an aerotank and we wouldn't have to buy different kinds of coils. The sales person suggested a davide bdc since it can use the aspire coils or the kanger duel coils. The tank came with 2 of the aspire coils so after showing me how to switch between the two types i went ahead and used one of the aspires that came with it. I have to say i really liked the aspire coil, everything was going great i loved the tesla, was getting a great draw from the tank and thats when it all went to crap. It was time to refill my tank and i wanted to put a different flavor in it so i was washing everything with hot water when i lost the little grommet that you have to use with the aspire coils. It kinda bummed me out but i thought no big deal, was going to use the kanger coils anyway. So i put in a kanger duel and it just sucks. The draw is horrible and i get hardly any vape or flavor and i dont know why. I dug out an old kanger single coil and tried it and it worked pretty well, not as good as the aspire but much better then the duel coil. Why is this? Any thoughts or ideas?
