Example Input: Funny thing - I bought some of these K-cups several weeks ago based on the strength of the reviews at that time.  I just got them last week and have had a few cups since then.  I'm using 8 ounces of water to prepare the cocoa.  I thought they tasted pretty good - reasonably chocolaty and smooth.  They were sweet, but not overly so, and the richness made me check the calorie count on the box.  60 calories - hey, not too bad!  It wasn't until now that I came back to place a review and I read the most recent reviews from others did I realize they use artificial sweetener.  Honestly, if I hadn't read it I would have never known - I didn't detect anything that gave me the hint when I drank it.  I think if you like a quick cocoa on the run you'll be happy enough with these K-cups.  Are they as good as a Swiss Miss packet from Costco?  Maybe not, but in my office I don't want to deal with getting powder on the counters and needing a spoon to get things mixed.  You'll sacrifice a little for the convenience, but to me it's well worth it.

Example Input: This is pretty good regular style soy sauce.  But it is not super-wonderful-better than any other good quality soy sauce you can buy in an Asian market.  The main value is as a unique gift.   In the Japanese soy sauce world, there are 4 types: regular, mild (usukuchi), for raw fish (sashimi) and light colored.  Bluegrass soy sauce is regular style.  Compared to Kikoman (a good commercial brand that is widely available) Bluegrass starts saltier, is flat in the middle, then ends with a complex & interesting flavor.  Kikoman is less salty initially and has a round, full flavor in the middle.  Doesn't have the complex ending flavors.  For me, the initial saltiness of Bluegrass is a minus and Kikoman's full middle flavor is a plus.  I prefere Kikoman, especially for dipping sushi where the flavor is more direct.  But I lived in Japan for many years and am used to the standard Japanese flavor.  I haven't tried Bluegrass blended in other food as a background flavor, which is how soy sauce is usually used.   Bluegrass is a perfectly good soy sauce.  Each brand has a different flavor and everyone has their favorite.  If you want a unique Kentucky gift for an Asian friend, this is different than the standard bottle of Bourbon or box of chocolate.

Example Input: I have been giving my dog these treats for years, thinking I was giving her something healthy.  I took her to my vet because she has been having bladder issues.  That's when the vet told me not to give them to her because they were made in China.  She said dogs have been getting sick from eating jerky treats made in China.  I can't believe I have been poisoning my poor little dog!  I will never buy another food product from CHINA!
