Bests & Worsts Reviews from Amazon

I tested these primarily for long-distance bicycle touring. Eight flavors with various caffeine content. All but Chocolate-Cherry (110 cal) have 100 calories. Flavors: All were fine. See details below. Chocolate-Cherry left a bitter after taste--possibly due to the high caffeine content. Consistency: Much like canned cake icing or soft, creamy peanut butter. Doesn't drip. I'd call it a paste or butter, not gel. Squeezability: Very good, even right out of the refrigerator (~40 deg F). Pros: The squeeze packet retains the top tear-tab that stays connected by a thin strip (see photo). Concerns: High caffeine content of some and bitter taste. Bottom Line for me: I really like the easy-open, attached-tab design making it easy to use one-handed. Also, I don't have to spit out the tab (litter) or grab it and put it in a pocket. I'll buy Mocha, Chocolate and Citrus for calories first, caffeine second, and slightly higher potassium content in the Mocha and Chocolate (80mg vs 55mg). Despite my being a caffeine addict, I am reluctant to use the 100+ mg varieties. With Chocolate (0mg), Citrus (25mg), and Mocha (50mg), I get the calories, potassium, and a gradient of caffeine content from which I can choose.
