I love my Keurig 2.0 and the wide variety of coffee in the pantry (30 varieties of regular, decaf, and even a few flavored). I drink 4 to 6 different coffees every day. It's great! The strong setting on the 2.0 makes a bolder cup than the older version (which I have at work).
Too bad the KOLD beverage maker has so many things going against it: Price of the unit; price of the beverages (4 for $4.99 in US); limited to an 8-oz. serving. Keurig hyped the machine early in the spring, then didn't make it available until late fall when it was cold outside and everyone's thoughts turned to hot cocoa, tea, and hot apple cider.
Keurig dropped the price to $199.00 for a few days around Black Friday. It's now selling for the discount (their term) price of $299.00. Those who like it have great things to say about the flavor of a freshly-made soda. The cost of unit and beverages are, understandably, almost universally panned.
Yes, the method it uses to create carbonation is cool, but I just can't justify having a small refrigerator running 24/7 for the occasional Coke Zero or flavored water. It's just as easy (and much cheaper) to use the 2.0 to make a large iced tea or coffee and to buy soda at the grocery store.
