I have been enjoying my three week old Pico with a Ego One Mega V2 in both wattage and S.S. TC modes. Last night I was reading about the "cotton burn test" and thought I'd give it a try. I tested in temp ranges starting at my vape temp of 310f and went up to 500f. Only at the 500f did the cotton show any signs of browning. I put the 1.34ohm coil I had been using that day back into the Pico and called it a day. This morning I am not getting any coil heat at my usual 310f in S.S. mode. I need to bump the temp up to 450f to get it vaping. The Pico still works well at 9w in wattage mode. I don't have another coil here at the offcie to try. Any ideas ?
