Ok, so I am fairly new to vaping. I own an e evic vt. My question is other then tasting burnt, how do I know when to change the coil. For instance ive noticed that after ive had a coil in for a week or so my mod will get really warm and ill get less vapor but there is no burnt taste. I'm also curious as to whether I can clean the coil. Ive cleaned the ego one mega tank several times but ive always just replaced the coil if it starts to taste bad. At this rate its costing me 5 or 10 dollars per week. So if it is possible to clean the coils on these id really appreciate a little info on how to do this. Also if anyone has any pointers on general maintenance id love to hear them. Thanks!
