The only issue I can see happening with this tank design are the wick ends being exposed to the tankful of liquid, if any of you have been vaping for a number of years you'll remember the old Stardust tanks and a few others that had wicking material exposed to the surrounding liquid, these wick ends will foul the fresh juice remaining in the tank if not changed frequently...especially if your vaping darker tobacco flavors.
Having said all that I ordered one anyway, it looks like it'll produce great flavor mad I just like the look...if it turns out to have the issue described above, and I believe it will, no big deal for 25 bucks. I'll report back once I test drive it for a few days.
