My daughter loves these snacks and can't get them in China where she is working now so I ordered them for her. Very satisfied and she was very appreciative.

Ex Input:
I like the taste, but the light roast was too light for me.  I find myself brewing smaller cups of coffee, hoping for a stronger taste.  Next time, I'll go for a medium or dark roast.  I think it was the medium that I had before and I really liked it.

Well this review is specifically for the Sea Salt flavor of these chips. I so wish I had tried another flavor, Dill or a couple others sound good but I will never know. I am not a fan of the flavor I had. Or better yet the lack of flavor. These tasted like health food more than I had hoped ( Like rice cakes ) and I wanted to write a 1 star review but felt it somewhat dishonest as the other flavor may be ok, others seem to like these but I will never try another and still have so many bags left. Grrrrr
