Ex Input:
When I got my Keurig brewer last month, I bought two different types of hot chocolate.  The Grove Square Hot Chocolate is far superior.  I have so far brewed it on 6oz and 8oz with good flavor at both sizes.  The flavor is rich and it leaves no residue in the bottom of the kcup (the other brand does, maybe I got a bad batch?).  Overall, I will happily buy this one again.

Heavily touted by the reviews, decided to try.  Mix is good, but not great.  Probably wouldn't buy again.
