I recently bought the Aspire Zelos 3 kit which includes the Nautilus 3 tank as an upgrade from my pod kits as the pods were burning out too quick with my choice of NET e liquids. Following all the instructions to the letter and washing the glass, using the correct wattage for the coils, all I get is a burnt taste, tried another coil, same thing. Got in touch with the seller and they suggested it may be the coils and are sending out 2 replacements, however today I thought I would try out my iTank M on the zelos mod and immediately it tasted burnt, when it was fine just an hour before on the vaporesso mod. Is there anything that could be wrong with the actual zelos mod (not the tank or coils) that could cause this too happen. I really would like to be forearmed with some knowledge if there is a problem and the seller won't refund, thank you
