I own 4 aspire nautilus tanks and just bought a fifth on eBay with a pack of coils for $28 which is really low. Both the coils and tank authentic codes checked out. The tank looks different that the other ones I have. The coils do not read the correct resistance and none of them work in any tank. I've been using these tanks and coils since they came out and have had zero issues until now. Is it possible to have a good codes and all coils being defective? I asked the seller to see his purchase order from aspire as he is selling them so cheap he would actually be losing money. The first thing I noticed on the coils are the holes are much larger. On the tank, I see a button instead of a spring below atomizer area. All coils taste burnt on any setting.
