Example Input: Tastes like pine needles!!! I've had other earl greys before and never have I thought I was drinking pine needle tea (Another reviewer said it was a bergomot flavor, i'm not educated enough to know)...  I bought this for my wife who can't have caffeinated varieties, and I can say i'm not a big fan.  The English Breakfast decaf is EXCELLENT.  I prefer my tea black, hot or cold, but this earl grey is not tolerable unless drank with a splash of milk and sugar (splenda for me though). It is undrinkable as iced tea.  I'd return this if i could. Avoid this at all costs, young jedi.

Example Input: I found this flavor of Primal Strips Spicy & (Hot Mushroom) to be one of the most salty foods I have ever tasted! It was an overwhelming salt taste and this flavor is just not for me. I could not eat more than one. This brand's Teriyaki flavor is better. The "jerky" is a bit soft, thin and oily. It has a strange texture that breaks into pieces that are more mushy than chewy. It is not as satisfying as the other "mock meat" products I've tried,  (2 examples are listed below). I suggest finding a way to taste one piece of this before committing to buy an entire case.  For comparison, I would recommend "Stonewall's Jerquee" (soy, vegetarian, available on Amazon). Stonewalls has a better, chewer,"meatier" texture, soft enough to bite into, but drier and firm enough to chew for a short while. It comes in 7 flavors, none of which were unpleasant, like this Primal Strips flavor.  Another tasty soy/meatless similar product is "Manna Soy Gourmet Meatless" (4 flavors, on Amazon). This comes in big, 4 pound, bags and 4 flavors. It starts out softer than jerky, but can be microwaved into dryer, chewy strips that are very satisfying. Very versatile for vegetarian/vegan diets and a good value for price.
