I have a confession to make:  I had one of these bars and a cup of coffee for breakfast, and it was actually not bad.  But the Amazon stars say "I love it" for 5 stars, "I like it" for 4 stars and "It's okay" for 3 stars.  So, I give it 3 stars.  I personally felt the coconut flavor was stronger than the chocolate flavor and I'm not a big coconut fan, but I am a chocolate fan.  It wasn't terribly sweet and I rather think I would have liked it a little better if it had been sweeter (but not too sweet - I'm kind of picky that way).  I liked the oats and the "gluten free"-ness of it.  I don't eat gluten, so that makes bread/bagels pretty expensive.  These worked out best for breakfast, although I think I used it as a going to bed snack a couple of times.  So, just for fun, I got some nutritional information from 1) Pamela's Oat Chocolate Chip bars 2) some unsalted, dry roasted peanuts and 3) some non-gluten gingersnaps.  1) 1, 1.41 oz bar  -had 9g fat, 15 mg cholesterol, 130 mg sodium and 2g of protein. 2) 1 oz (40 nuts)  -had 14g fat, 0mg cholesterol, 0mg sodium and 7g protein. 3) 5 cookies (30g or 1.06 oz)  -had 6g fat, 0mg cholesterol, 85 mg sodium and 2g protein.  I think that each of these snacks might serve at one point or another.  If you are looking for high protein, then neither the cookies or the Pamela's bars would do the trick, confirming that the Pamela's bars would be more of a snack than a meal.  So don't eat one of these with coffee for breakfast.  Ever.

There should be an option for a 0 star rating because that is what I would rate this item. First, the sampling was to include 9 varieties but included only 7.  It appears that the two flavors out of stock were not substituted with two other flavors but instead a few more of the remaining flavors were tossed in the box. I had expected that when a limited edition coffee flavor such as Island Coconut was out of stock, it would be replaced with a different limited edition coffee flavor.  Same thing for the Half and Half Lemonade. Second, the order was not balanced.  Of the 7 flavors I did receive, only 2 were coffees, the remaining 5 were teas. The concept of a summer sampler set is a good one but the execution here was an epic fail.  The order is being returned today.
