I don't own one of these Enduras, bought some for my iClear 30s. These coils should work, said Innokin, and they do. Exact the same way as the iClear 30s coils do. Beware to close the top cap tight, otherwise the atomizer will leak. I'd like to see more Endura coils with 1.8 and 2.1 ohm, would buy a bunch. Cotton filled coils provide a better taste than the old fashioned one with silica rope inside.
