The vow of silence is officially over! Thank you Bloog for finally releasing the Coffee flavor in refill liquid! I have bugged CS with "when,when,when?" for this stuff for a long while! Ahhhhh...sooo good! I tried MANY coffee liquids, but they all either tasted burnt, or had all kinds of other flavors added to cover it up or mute it. Bloogs is just a nice, clean, smooth, full flavor COFFEE!! If you like coffee, you'll love this.
