Hello, just want to enquire if the coil on the wick of the ce5 clearomizer is vital for the product to work? After using my ego x6 vv battery and ce5 clearomizer for a few days, i realized that sometimes my product does not work when i press the button(it doesn't heat the e juice). I also know about the non-firing center pin issue but my product still does not work. I have never once dropped my product. Do you guys perhaps know the reason? Just to mention, i lost the coil on the wick of my ce5 clearomizer so i was wondering if that coil is vital for the product to work. Thanks
