Example Input: This was my first experience with a new product, and I was not impressed. The coffee did not taste much different than the average Starbucks coffee, even though it cost 2 dollars more per pound then Starbucks. I'll stick to making the 10 cups at home in an Espresso machine, which is quick since it's less costly for me and better tasting every day. Next time around, I'm paying 3 bucks worth of premium beans and get some good crema.
Example Output: Bad review
