Example Input: I got the sea salt and vinegar chips from Kettle.  I am used to the Salt and Vinegar chips in the white bag if I am allowed to say that.  Anyways, my first impression for this is wow at all the chips you get for the price.  I got the 9 0z x 12 bags and wow it is so many for the price.  You can tell they are high quality chips just from the packaging, also.  Well being used to the cheaper chips I wasn't expecting how mellow these things are.  The ones I am used to have a really sour taste to them which I didn't mind but they had tons of flavor.  These chips don't have any sour to them at all, and taste just like them but a lot less strong aftertaste.  If you want to try out Salt and Vinegar chips I suggest you try these out first.  So, for the price and how many you get, these chips are definately worth it.  They are thick and crunchy like the more expensive chips you get at high quality restaurants.  I recommend these, 4 stars.
Example Output: Positive

Example Input: I have tried different brands of hot cocoa from dark to milk and the Grove Square milk chocolate k-cups have by far been the best.  They're big critics in my family and they have given two thumbs up.  I would recommend anyone who enjoys hot cocoa to purchase this brand.
Example Output: Positive

Example Input: These are really good. I like to make them with a little extra milk so that they are thin. I can't even tell the difference between this and regular pancakes. It's worth the price for my family.
