I've had a handful of good mods over the years but all of them lacked in one way or another. I got the Pozz X about a month ago and can finally say that I have found the mod that meets all my expectations. The 0.8-ohm coil with 25mg nic salt, set to between 8 and 12 watts, is absolutely perfect and lasts all day vaping heavily. The 1400 milliamp battery has never left me stranded as it lasts, on average, almost a day and a half, at these low watts. These RPM coils have probably leaked less than a milliliter all together and last a full week at approximately 4 MLs daily. My one critique would be that the airflow control doesn't do much but as I am a direct to lung vaper, I'm not bothered by it. That said, if mouth to lung is your style, the 1.2ohm coil has smaller air holes and is much more restrictive. I have no doubt that I'll have this little mod in what used to be my lighter pocket for years to come.
