This Keurig K-Duo is like the best of both worlds in one compact machine - a single serve brewer that accommodates our biggest travel mugs and a large glass carafe drip coffee maker. We have been using the Keurig 2.0 for many years, and that was fine on weekdays when my husband and I were making our coffee at different times. We were interested in a carafe-based drip system for the weekend or for parties, when we wanted to make a big pot that could be shared. I tried a different brand of carafe plus single serve brewers previously and was not pleased. I was concerned this Keurig K-Duo would be too big for my counter from the pictures online, but to my surprise this machine was not much wider and the Duo was actually shorter in height by around 1.5". We have been using the new brewer for about a month now and are gradually getting used to the new brewer. Below are my assessments so far: Pro: -Single serve brewer accomodates our tallest travel mugs, including ones that never fit in the Keurig 2.0, and our biggest ceramic coffee mugs. -The glass carafe is large and wide opening top that is easy to clean. -System warms up quickly when turned on (although it is louder than the Keurig 2.0 was) -Single serve portion has a "strong" button to make more strong flavored coffee. -Drip coffee portion accomodates 12 cups of coffee. -Water reservoir is wide and easy to clean out. -Compact size fits easily under a cabinet. Cons: -Water reservoir is on the back and unless you have it at the edge of the counter, you might have to spin the machine around to take the reservoir on and off. -The water reservoir seems smaller than previous models. -The controls require a pattern of button pushing, instead of a menu of preset options as we had on our Keurig 2.0. It is easy to figure out, but when you trying to get coffee made as you are rushing out of the house, it can be frustrating if you didn't hit the 'start' button and the machine fell asleep on you and didn't make your coffee. (This is a nitpicky issue of mine, but just a warning to be sure you hit the "start" button and hear it starting to brew.) -Buttons and controls are on top of the machine - consider this when selecting placement of the device. These controls could be hard to see if you have low cabinets or something over the device - I prefer the front back-lit screen display of the Keurig 2.0 in this aspect. A few other things of note are that this device does not come with any basket style coffee filters for the drip coffee/carafe side. You will need the 12-15 cup max size basket style filters. Also there was mention about using a water filter in the reservoir but there was no filter and no filter holder included with this device. I believe there was a filter holder and a sample filter included in our previous Keurig 2.0 machines, but no filter items are included with the Keurig Duo. Overall I like this new Keurig-Duo device so far. It just takes some getting used to after we have been using the old single serve Keurig machines so many years. So far it is working with all of my k-cups and with our reusable k-cups we put loose coffee in, including a set of reusable k-cups that had pieces sticking out on the sides that didn't fit in the Keurig 2.0 machine.
