[Q]: Makes great coffee for about 4 months. Cheaply made product. All pipes inside are cheap plastic. Even a $25 Mr Coffee has copper water pipes in it to carry the 190 degree water but not Keurig....all plastic water lines. Heat plugs the lines up in 3 to 4 months. Piece of cheap junk made to look pretty. Save your money
[A]: Negative

[Q]: 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!
[A]: Positive

[Q]: When you have a craving for a sweet but you don't won't too much, this bar is just perfect. It's yummy.
[A]:
Positive
