Used JoyeTech clr's exclusively rebuilt them etc now have hundreds of them for Mrs and i and no need really to make new coils just re-wick them but do save them for gaskets etc like i really need to Nope but just do for some reason.
Then the innokin ares came out never tried a rta and will just say its very easy to coil and wick and also to fill happy to have 3 ares plus several clr's set ups in rotation.
