Here is another noob question that i have. I keep getting a dry, kind of burnt taste from my clearomizers, even the new ones. It usually happens when they are about half full. Do i need to keep it constantly topped off to avoid getting that burnt taste? If so, I'm not sure a clearomizer is the way i want to go in my vaping future. Would a cartomizer be a better choice? I'm loving not smoking cigs but there seems to be quite a bit of maintenance to vaping. Thanks for everyone's replies so far. Great help. Plz excuse any typos, sent from my phone.
