Ex Input:
I recieved a Keurig K-Cup Brewer for Christmas with sample cups of coffee and tea but no cocoa so I tried this brand and I like them but I haven't tried other brands yet to compare with. I would buy these again until I find one I like better.

Ex Input:
I was introduced to the Blair chips by a friend. I mostly ignore potato chips because I really don't like them. However, these I like the most among all the chips in the Blair line. They are savory and can be eaten rapidly. The hot chips are good because they are so hot, I cannot eat them fast. I am so happy I cannot get them at local stores because I would eat them all the time.

Ex Output:

Ex Input:
It doesn't have a whole lot of flavor, but most light roasts don't. It does have a unique flavor, but is kind of rich and tiring, so I recommend you mix it with other coffees to make it taste better and make you other bland coffees taste a little better.
