They list several different Eleaf EC coils but name them differently. But all say eleaf is the manufacturer.

Like this one I'm posting under (listed as dual coil, which is correct) and this one and this one. These 2 are listed as "Ijust" but eleaf has no ijust coil, just EC coil, that fits many of their tanks. But these two aren't listed as dual coil. Eleaf only recognizes 1 EC coil with 2 different ratings, the 0.3 an d0.5 ohm coils, both dual coil.

So are these all the same, with dual coils, but just listed differently?
