Spark tastes AWFUL!
Many of my colleagues swear by Spark. I have resisted trying it for a few years now, only because I don't love the idea of caffeine/chemical drink mixes. I finally gave in and gave these samples a try. I have been through 4 flavors and they keep getting worse and worse. Admittedly, I'm mixing them in probably 20 oz of water, and not the 8oz recommended. I can't imagine what a concentrated taste would be! Apple, grape, and watermelon are all undrinkable. Pink lemonade was tolerable. Fruit punch, mandarin orange, and mango strawberry are still in the lineup to try.  The immediate smell when opening a package is a mix of 1980's chewable vitamins, dogfood, and burnt hair. Really--I'm not trying to be dramatic. The taste is whatever the flavor is, but you can still smell that awful smell. The energy from it is unremarkable, and I probably prefer a redbull for the effects I'm looking for (at least those taste like sweet tarts). I'm still making my way through the rest of the flavors, but as it stands now, I will be leaving this taste test failure behind.<br /><br />Seller feedback would be 5*. They arrived on time and in good shape.
