PROBLEM: I enjoy them a lot and so does my son. I have to say that this kind is one of my favorites. It is full of peanut butter flavor that you forget that it is only 100 cals. As for the amount you get in the bag, it is more than I expecting so I was very happy.

SOLUTION: 5

PROBLEM: Next time I will order only the original flavor.  The other flavors did not suit me.  Too much of an aftertaste.

SOLUTION: 3

PROBLEM: The first couple of bags were great. Really fresh, smooth, great taste. I thought I'd found the perfect coffee bean!! The next 5 bags .. stale. I canceled my order and went back to buying whole bean coffee from the supermarket. You pay a little bit more, but I've found that most of the time, the supermarket coffee is fresher. I prefer the taste of Weaver's but too many stale bags.
