Hello everyone. I recently bought my first ever vape, a SMOK Vape Pen 22. I ordered it from DirectVapor. Everything came in the package fine. Both coils, however, seem to only last me a few days at the MOST. I start getting a horrifically bad burning taste in my throat, almost as if I chucked something up and have the burn still in my throat. I've checked each wick, and they look fine. I'm a vaping noobie, but I made sure to pre-drip each coil thoroughly and let it soak in for at least 10 minutes. Then I did it again, just to be safe, waited another 10 minutes, and finished building it. Once done, I filled it with 0% nic, Dollar E-Juice Club Churros & Ice Cream juice. I let it sit AGAIN for at least 20 minutes, before vaping. Each coil starts vaping perfectly for the first few days (the first one lasted much longer than the second, however.) I've made sure not to drip e-juice or water anywhere it's not supposed to be, and I charge it sufficiently before vaping. I only draw for a maximum of 4 seconds, but usually one 2 seconds at a slow draw. Am I doing something wrong, or did I get some iffy coils? Again, the wick looks fine and I don't imagine I've used it enough to burn out both coils in only 6 days. I don't chain vape, a max of 10 pulls an hour. Any help would be appreciated. Thank you in advance.
