Ex Input:
Switch Orange Tangerine is ok but not what one might expect.  First of all, there is more apple and grape juice in here than orange or tangerine (this will not be a surprise if you are familiar with the other flavors as that is also true with them).  Switch basically is carbonated juice.  The taste isn't a bad and it is supposed to be healthier than soda (which can be debated).  It is a reasonable drink for snacks but if you are going to need several if you are actually thirsty.

I ordered these to make s'mores. I liked the ingredient list, no HFCS. However, they come more like a box of Wheat Thins. They are not large enough for s'mores, and many of them are broken upon arrival. They do taste good though, as a sweet snack.

I'm a big fan of Buffalo chicken and beef jerky, so I thought I'd love the Jack Link's Flamin Buffalo Chicken Nuggets.  I was wrong.  I bought the Steak Nuggets as well, which aren't as good as Jack Link's jerky, but definitely tasted better than the Buffalo Chicken Nuggets. To put it bluntly, they tasted like an old chunk of salty chicken with a slight Buffalo flavor.  They're not very spicy, I was expecting more of a kick.  They also smelled a little funny.  I'd give Buffalo chicken jerky a try, but I won't be buying these ever again. They're OK, but there's so many better options out there.
