Ordered on a whim.  My first "Grove Square" purchase.  Great for the family's occasional cocoa desire.  Being a K-Cup it's fast and easy.  Was a little worried the cocoa might leave some after taste in my coffee, so far so good.  Great cup of dark, rich cocoa.  Maybe could taste a LITTLE better if it was from a gourmet brand you mix yourself with steamed milk.  The ease and simplicity, and lack of clean up, make this a better option for me.  Will order again.  Nice to see it on subscribe and save.

I have been looking at this product for a couple months and finally gave in.  First of all, the name got my interest!  The taste is delicious BUT I'm having problems with the directions!  Haven't figured out if it's actually a hot beverage or do you put it in a hot beverage?!?!?!?!?  It has a scoop (small) and says to put that in a cup (instructions for 8 oz.) and then put a couple "shots" of hot water!  Shots of water????  And you can add frothing milk.  Hum!  Confused but I guess I will work with it.  Hope it doesn't take the whole container (very large) to figure it out. I would have given it 5 stars had I understood the instructions!

I bought these bags b/c I thought they were tough, thick nylon.  I guess these bags would work perfectly fine if you're just using them for transport.  I needed a really tough one like the KBR guys try to sell us for $8 here in Afghanistan...2 of these bags are already in the trash after only 2 uses each.  They wash the laundry in the bag and both have ripped after only 2 uses.  I gave them a 3 b/c they are not that bad..just not what I was needing.  The seller was awesome!  I received the bags here in Afghanistan after only 6 days from the original order date so I have to say the seller was very expedient.
