I haven't posted in awhile. I felt this needed to be brought up to attention with the smok tank series. I noticed tanks that become obsolete in sales will now be replaced quite quickly in local shops and now even online. It's a major inconvenience to me and to others as well. The series of tanks I noticed that raised quite a few eyebrows are the TFV8. In fact... while in the shop people were calling in while I was talking to the fellow guy at vape city in skokie "You folks have any more tfv8 coils", customer asks... Vendor: "Sorry man, all out. We will no longer be selling the coils anymore. But we will have the newest TF coming in soon". Then it hit me... The TFV8 wasn't out that long. Now I feel forced to buy a new tank because of coil shortage? I've never seen such a phenomenon. Not only that, but also a feeling of dread similar feeling needing to upgrade to a new phone when instead would be satisfied with what I got. How did this turn into a trend of the norm? Even more so, the single coil for the tfv8 can't be found anywhere. The coil lasted more than the other double, quad, and other coils I've tried for this thing. I'm going to have to look for something else and ditch the tfv8.
