I took one of my almost finished BLU cherry cartos. I popped off the cap and dropped in some Johnson Creek "Merlingo" cherry flavor 100% VG into he filament. Let it set 10 minutes, and got a pleasant surprise. It was my first time refilling a BLU Carto. The vape was thick and flavorful with a nice throat hit. I am waiting on my Ego mini 350 mah with vision tank that I bought for 14.95, and some juices from Vape Dudes 40% off, but I gotta tell you, if you keep the BLU batteries charged, you get a very enjoyable vape.
