Love it
I tried the espresso clif minis and I am very impressed. As far as the caffeine it is defiantly quick boost of energy, I don't drink coffee or other caffeine drinks often so I can still get a jolt from small doses of caffeine and this does the job. I love the size its only one or two bites and whenever i'm felling a bit groggy I can eat one of these and get going.  The flavor was surprising, I was expecting a very bitter caffeine flavor but while it is still a bit bitter its actually not only bearable but enjoyable. Overall I am very happy with this product and would recommend it.
