My brother owns a Keurig one cup coffee maker, which is an amazing device. I, however, don't drink coffee. When I came across these Hot Cocoa K-cups, I took a chance. They're incredibly good, and it gives me a chance to share a hot drink with the coffee crowd without having to boil water or milk. This 24-pack is priced well against the coffee K-cups as well.

Ex Output:
Positive

Ex Input:
This is the best tasting stevia powder I've tried. Most other powders have a weird after taste but this one doesn't. I recently bought a 5lb bag of it online and I'm making my way through it.
