Can anyone help me I do not know what I am doing wrong. I have a cool Fire ultra battery and have bought a SMOK brit mini flavour tank with a 1.2 coil and a 0.2 coil. It says that these can be run at 25w and 20w respectfully but the first one lasted 2 days and the second one keeps tasting burnt. It is costing me a fortune in coils since I had the same problem with my previous ones which were nautilus x. I must be doing something wrong. Help.
