It seems crazy. I've only had this mod since Wednesday.. Only light vaping the first few days. First battery lasted almost two but I really barely used it. Today I definitely used it, solely. But I didn't chain vape it. It was actually turned off more than it was on. I hit it 7-8 hits about 5 seconds at a time intermittently and it's only at around 22 watts in non TC mode with a standard 0.5 ssocc. But yeah I'm on my third 25r5 of the day. Now I'm wondering if I didn't get an old or dysfunctional Nebox or a set of crap Samsungs. 4 from RTD vapor.... Anyone ever run across this?
