This first Kanger coil lasted about 2 1/2 weeks or so. I wasn't sure the coil was burnt, other than the fact it wasn't working as well as it had been. Changed to the second Kanger coil, and it was great for maybe 5 days. Again I wasn't sure what was going on, so I took it in to a local shop and they said the coil was burnt. So I got a new coil, 2.5 ohms. I'm not sure what percentage the juice is, but its 18 on the nic. I also just got a bunch of new 1.8 Kanger coils that I haven't tried yet.
I'm still new to this and don't know much, which is why I came here to learn more from others! I don't even know the difference between atomizers, cartomizers, and clearomizers. I just know that the manager from the local shop told me the bottom feed tank was better, so I got it!
