Example Input: My son and daughter-in-law told me about these chips and they purchased a few bags at a store and I will say they are higher in stores then you can get them online on Amazon. They brought me a bag and I was hooked! So I ordered popchips online and they are the "BEST" chips!! There wasn't a flavor I didn't like or that my family didn't like. I am a (chipaholic) and these are better for you and a great tasting chip. I highly recommend these to anyone that can't do without eating chips either with a sandwich, hamburger, or just to munch on midday. You won't be dissapointed.
Example Output: 5

Example Input: At first, I was concerned about ordering Babka online but I kinda missed this one. As I tasted it the only thing I could say was : "wow". I will order this again for sure.

Example Input: Note: This is my first review of a product that is not a book, so please forgive me if I miss something. I'm not a huge fan of fruit drinks like The Switch, but I decided to go ahead and give it a shot. After having my first drink, I can honestly say I wanted to hate it. I mean, seriously, I'm drinking this can of 100% fruit juice with carbonation and reading all these really stupid quotes all over the can (i.e. "100% of what I want in a soda, 0% of what I don't"), wondering how much a 8.3 ounce can of this junk costs (thinking somewhere in the neighborhood of $2.50 or $3.00; and thinking, if I wanted to drink some juice and would drink some juice! I couldn't stop thinking about what is so special about carbonation that I would want to drink this over a glass of OJ. I wanted to scream! However, I kept my cool, and finished the drink. There was something about this particular flavor that was enjoyable, but not engrossing. There was something in the aftertaste that I did not like, and I think it had to do with the tangerine juice. Tangerine's aren't my bag, either; but it was tolerable. After discussing this product with my wife (I know, this drink apparently also contains the conversation starter attributes, bonus points for that I suppose) she was like, "this sounds great. Is it like those <a href="http://www.amazon.com/gp/product/B001IW25RK">Izze POMEGRANATE SPARKLING 100% JUICE DRINK</a>??" I responded: "Um.... I guess so..." I then also looked up the price and learned that I had grossly overestimated the price of a single can (being just over a single dollar). Despite my wanting to hate this product, I've decided to step out of my anti-contemporary culture box, view this product for what it is, and give it a middle rating of 3 stars. I can see the attraction; I can see the appeal; I just won't ever buy it. I'll stick to my glass of Orange Juice and Tang any day. Good drinking, J.Stoner
