question:
I was so excited to get these k cups and immediately filled 10, for future brewing, with my favorite coffee.  I tried one right away...  the coffee started running down the front of my Kreuig.  I thought I had filled the cup wrong and maybe not had the lid sealed well enough.... but when the coffee was done I opened the k-cup slot and found a melted wrinkled container.  I have subsequently tried more of the orrigional 10 that I filled, after carefully checking that they were properly put together, and all melted in the same way.  I have since thrown the rest away because I was tired of the mess they created!  Don't buy these... they do not stand up to hot water.
answer:
Negative


question:
This makes the best tortillas.  That is about all I use this for, so it lasts me awhile. Mine cost about 1/2 the price as listed here, but it was on sale where I bought it too.
answer:
Positive


question:
Very high quality dulce de leche from Argentina. Compared to most brands, it's a bit lighter colored, and the taste is more subdued and milkier. You may or may not appreciate this, as it's not the classic taste that you expect from commercial dulce de leche, but it's by far the closest to the homemade dulce that my grandma used to make. For this, I'd give it 6 stars if I could!
answer:

Positive
