[EX Q]: We've only used this once, but it kept us awake most of the night.  We were surprised because it's decaf, but we couldn't sleep for hours after going to bed.  Tastes good, though.
[EX A]: 3

[EX Q]: Not bad, but there are better gums than this one. At the beginning is a big explosion of flavor and sugar like sensation, but after 5 minutes is gone.
[EX A]: 3

[EX Q]: I read the reviews and thought, I like salt. I thought the saltiness was on the exterior of the jerky.  There is very little salt taste on the outside of the jerky but the saltiness comes out with every chew. The strips are about the size of a chopstick or a very thin pencil. 12 ounces for $20+ is way too expensive.  There is very little beef flavor but too be fair it is probably covered up by the salt.  These taste very similar to the chopped and formed cheap jerky at the convenience mart that you swear you will never buy again but much more salty. The amount of salt made my tongue numb, if you want good jerky keep looking. (Jack Link's Smokehouse Beef jerky strips, wood smoked 30-count jar)
