2 weeks my ....  these things only last me 2 days.  I've tried priming them every way you can imagine.  pouring juice on the mesh, into the holes of the coil, dropping juice down the drop tip, letting it sit for a little bit, sucking on it really hard to get more juice in the wick....nope still 2 or 3 days max.  Been through about 15 coils now i buy them in the 5 packs.... 
also i vape at 30w with an istick.... manufacturer recommends 20-30W
