The taste is great but most of the crackers are broken.  I am maybe getting 12 whole crackers per box.  The first time I ordered these there were several broken but this time there are more broken than whole.

Ex Input:
This hot chocolate is pretty blah. Not very chocolatey and certainly not very strong. It's not the fault of the Keurig -- the Cafe Escapes Dark Chocolate is way better.

Ex Input:
If you enjoy the taste of Bacon, you may like these. If you're looking for the SW Ranch flavor indicated, expect Bacon flavor instead.  They have a nice crisp texture that's satisfying. I personally don't care for bacon flavored anything, so was disappointed to find South West Ranch flavor MIA. I tried & do like the plain sea-salt flavor.
