I've had my PockeX for nine months now (since September 2017) and use it daily.
Recently it has started changing the taste and colour of the liquid. I use Element NS20 Frost which, I believe, has a high VG level. The liquid is gold in colour, in its bottle and when I initially fill the tank, but once I start vaping the liquid turns a dark brown and the taste is wrong.
I have fully charged the battery, correctly changed the coil multiple times, thoroughly cleaned the device before trying to use again, and even tried using different liquids, but the problem always recurs.
I was wondering if anyone else has had this problem and if it might be due to a component of the kit that I can't change, or whether it's simply due to the age of the product? Either way it seems off-putting in terms of longevity for the PockeX...
