Finally, a tank that works well with dark, thick juices! Ive been burning through coils like crazy with all of my dual bottom coil tanks when vaping my favorite juice, which is a combination of caramel, cappuccino and hot-buttered rum. I was about to give up on the awesome flavor and settle for my other juices as I couldnt justify burning through heads every day, and rebuilding them only gave me a little extra time. I still have my trusty Halo Triton top coil devices that I sometimes use as pocket vapes, and found that they lasted a week with the same juice, but I dont like plastic tanks and have been looking for a glass top feeder. I was about to give up when I found the Vision Vivi Nova V-Fate glass units, which have dual top coils and the long wicks. Wow, what an awesome tank! Glad I stumbled upon them while online at MVS. Ordered on Wednesday, had the tank in 2 days, and Im glad I didnt give up on vaping altogether. If you like the darker, thicker juices and arent having any luck with the bottom coil tanks, give these a try. Ill keep using my bottom coil tanks for everything else, but I can still vape my favorite flavor with the V-Fates. Im stoked!
