Just received Monkey Buns and Monkey Beach in the mail and tested them. Their born on date says Oct 2013 so I'm assuming they need to steep a bit, however they are both great out of the box. They also threw in a sample bottle of Chimpan-Tea which is supposed to be a green tea flavor, have not tried it yet.
Monkey Beach tastes like some sort of smoothie. It's awesome!
Has anyone used monkey buns? Does it ruin plastic tanks? I have it in a T3 and I'm a little worried cause it's very cinnamon-y.
