I am so glad I ordered this; it is the best dulce de leche I have been able to find. I had read about this somewhere and am now convinced that many people are not familiar with this product. If you like anything caramel, you'll love this!

Ex Output:
Positive

Ex Input:
in my opinion these are heads and twos above any pickle that you normally find at your local grocery store. a lot of nice, sweet, pickle flavor. I probably won't buy again off of amazon because of shipping charges, but if i ever see them locally, i'll buy a bunch.

Ex Output:
Positive

Ex Input:
I bought these when on sale through Amazon. Nice crispy thick chips. Definitely a great buy if you can catch them on sale.

Ex Output:
Positive
