I got mine yesterday, as well, and I found that the pre-installed wick and coil were (for lack of a better term) jacked up, and not in line with the juice I was using (Boba's Bounty - too thick for 400x400 mesh, I think). I was getting burnt, dry hits no matter how much I fiddled with the coil and the resistance was jumping from 1.3 to 2.1 ohms. Having never used an RBA before I thought this might be part of the break-in process, but I was definitely wrong. I started over with a 325x325 mesh and made my first coil and I was pleasantly surprised to find that it was not all that difficult. Now everything is working much better and I am getting nice, clean hits and it hasn't even broken in yet. I am still not 100% sold on this setup but I am going to give it some time. I really wish the tight draw caps were still available somewhere....
