Last night was a great moment when I got my first mesh wick working 100%. It came out @ 1.8 ohm, looked clean and done well and vaped amazing for the whole tank, not one bad hit. I was vaping at 3.7v on my vmax v3 telescopic. I took the cap off to refill, a few puffs in and it was burnt. No matter what I did I could not get rid of the hotspots. Is there something I need to do maintenance wise to keep it hitting well? I see people take these on the go with them and it seems you would be adjusting the coil every hour or having to replace it daily.. Any tips on getting some longevity out of the coil would be greatly appreciated. Thanks in advance.
