I have had some horrible times with those coils leaking, Until I found out about the contact wires protruding thru the rubber gasket on the bottom. Now when I get a new 3-5 pack the first thing I do is pull the silver contact plate off the bottom, cut the first wire you see flush, pull the o-ring and cut the second wire flush as well, put the o-ring back on making sure the little protrusions are lined up with slots and that you have one wire inside the ring and one out reinstall the bottom and no leaking. I cannot tell the watts on my prince tank, it is on a stick, however the flavor it good running fruity flavors pg 70/30 , your ohm are .17 for that coil and I am getting a good use time on it as well. It seems smok has horrible QA on their replacement coils
there is a vid on fixing the leaking problem but for some reason it is not coming up or would post link
