About 6-8 months ago I bought my new vape I have a Reuleaux RX 2/3 and I was using the baby beast until the TFV12 came out. At the beginning I would get great flavor from the TFV12 no matter what coil but these past 3-5 months every coil I bought would not give me any flavor or it would give me a cotton flavor, 2 Weeks ago I bought the RTA TFV12 hopping that would fix the flavor problem. I built the Triple rba by myself and I would get a cotton flavor, I let it stay for a couple days hoping it was the cotton that needs to break in but it didn't go away no matter what juice I used, so I took it to my local vape shop to have an experienced person rebuild it for me because I thought I messed up, but I'm still getting either a cotton flavor or no flavor at all and I can't taste the nic on my juice, idk what's wrong could it be my mod?
