Lately I've been experimenting a bit with different flavors and different vendors and I have found an amazing mix! I filled about 3/4 of a fresh Ego-C tank with QuickNicJuice Enigma,a few drops of marshmallow from JuicyVapor(I'm sure most any marshmallow would work though) and a few drops of BackwoodsBrew Espresso and it is definitely the best tasting vape I've ever had,not to mention it makes the room smell like a Toll House Cookie factory inside a Gloria Jeans! Yeah it really is that good
