As someone who arguably has a minor addiction to coffee, you can trust me when I say I have tried all of the single cup coffee makers. While other single cup makers, like the Keurig are good, I found the Tassimo to be the best. Some of the functions that I enjoy are that they do more than coffee and plain tea. For example you can even have steamed milk for an espresso or chai. That is the number one reason why I say this is the best single cup maker out there. Brew Performance On average it takes about 2, if that, minutes to make me a fresh hot cup of coffee. Ease of Cleaning Very simple, the bottom compartment that is meant for an over flow situation slides out, and you can simply just wipe down the rest of the machine. Ease of Use It's simple, you turn it on, start the brewing, then have the option to add more water as desired. Design Efficient. It's a tiny bit bigger than your average Keurig, but not by much, and in my opinion it is still a better choice than other options out there.
