I have both and use neither of them. Both have drip tips but will need coils.the k1 coil is still good but I would imagine you would want to put a fresh one in.if anyone needs them let me know I can send them to separate places or both to one.they helped me and my wife get off of the cigs,time to pass them on in hopes to help someone else.
