This practically falls under the category of healthy snack - well, almost.  Single serving bags mean you won't be overeating and the fact that these aren't in anyway greasy because of the way they are made is a huge plus.  Nice crisp crunch.  The bags are filled with air, which for the most part do a good job of keeping the chips whole.  On the case that I got, though, two bags containted nothing but broken bits.  Of the rest most only had a couple of broken chips - some no broken ones at all.  I also noticed that you don't find nearly as much coating from flavoring on your fingers as I've experienced when eating other chips.  Purchasing it by the case to try out all of the flavors is a good idea and a decent value.  Some of the flavors are incredibly strong, to the point that I don't like them, so I won't be ordering this mixed case again.  Salt and Pepper just tasted like pepper, making this a very hot tasting chip.  The Seasalt and Vinegar is really strong on the Vinegar, which is a taste I don't enjoy.  I love BBQ flavored chips, but again, this was kind of strong.  I probably wouldn't purchase the BBQ ones in the future, but wouldn't say no if someone offered them to me.  The Original is really bland compared to these others, but not bad.  The ones I liked the most were the Sour Cream & Onion and the Cheddar, both with milder flavors.  I'd give this 5 stars if I liked all of the flavors.  Definitely high marks for the type of chip and the size of the serving and the fact that you can try all of the flavors in one order.

Come on Amazon, give me a break.  Powdered tofu?  Get in some real food and I'll buy more from you. I went looking for table sugar. You've got 100 weird kinds of sugar (that you expect me to buy in bulk!) but NO just plain sugar. I'm not eatin' any more of this rice and tofu bread either.  Sorry I just had to rant.

The product says a twist because of carbonation. Well after pouring the drink over 3 pieces of ice the carbonation was gone.  The carbonation is definitely light and does not last.  As far as the taste goes I did not care for the taste at all. It left a bad after taste in my mouth I cannot recommend this product. I will stick with regular juice at a much lower cost.  To be fair I gave it two stars because my wife thought it was OK.
