Hello, I switched to the Aspire Atlantis tank after horrible experiences with all Kanger products. The first coil that came with the tank lasted me over a week. Since I changed that FIRST COIL (with the replacement coil that came IN THE BOX) I have been burning through ONE COIL PER DAY IF NOT MORE. I have been priming the coils appropriately, letting them sit for 10 minutes, dry hitting, then starting on 14w and moving up slowly never going past 20w and I have NEVER HAD a coil last more than one day. I replaced the tank. Same issue. The first coil was a great experience, but I have been going bankrupt replacing these coils! I called Customer Support and they suggested that I post here as the moderators are quick to respond. At $20 per box of 5 coils and with no one (including the Aspire rep I spoke to) having ANY IDEA how to stop this problem, I am at a loss. I shouldn't have to spend this much money on coils, and shouldn't have to buy yet ANOTHER tank. Your company makes great products but I am becoming increasingly frustrated at my situation. I implore you for troubleshooting, and perhaps some coils for my trouble! (And I have indeed verified each and every box of coils is authentic by the scratch pad). PLEASE HELP!
