Input: Consider Input: Enjoyable tea with a refreshing taste. The 16-count Pack of 6 represents an excellent buy compared to store prices.

Output: Positive

Input: Consider Input: This 24-pack lasted about a month, and I sampled all of the flavors but only got to eat the barbecue flavor once, as it is my wife's and my favorite. So, I reordered just the barbecue. Great snack for 100 calories. I've purchased the reduced fat Pringles 100-calorie individual packs before, and you get a lot more chips in a Popchips bag than from Pringles.

Output: Positive

Input: Consider Input: I switched to this food from Blue Buffalo. I hate to say it, but around the time Blue started doing tv commercials the food started upsetting my dog's stomach. Perhaps that's a coincidence, but it was a reason to switch regardless of the timing. The Newman's food has been great. My dog loves the food. He has been energetic and in great health. Not much more that you could ask. The bag of treats that comes in the 12.5 lb bag is a fantastic bonus to every bag.
Output: Positive
