Hi all, i am pretty new to vaping after turfing the bad cigs. I started with an Aio Joytech 2ml pen type vape but it did not do it for me. Went to an Aspire K4 and thought "damn, this is it, taste, vapour". But soon it was "hmm, reveiws said 3 week coil life whats with this 3 to 4 day max im gettiing?" I prime them, let em soak for 15min, and even pre firing draw without hitting the fire button. Still the same. Have even had some bad coils straight up as if they were days old. So id like to ditch tbe K4 for another simple fire n go like the I just S. Question please, does the I Just pull as easy as the K4 on the draw/drag and how long do the coils last? Im sick of the K4 rubbish coil life and DOA coils. What if not the I Just would replace it for full taste and big vape hit and good coil life? Id want a discreet pen type with at least 3.5 ml to 4 ml tank. Thanks and cheers in advance.
