It does its job. Makes the coffee quickly and well. The thermal works well too if you enjoy taking the pot of coffee with you to work in your office. Brew Performance I would review it as above average but not fantastic. It does well and the coffee tastes good . But I believe they could improve on the overall performance of the brewing on this machine. Its a thermal one I use it to do one of two things for when I'm entertaining guests or the other is to bring it into my office to work. Also it does allow you to shut off the coffee maker itself and remain warm for your next cup. Ease of Cleaning This is made very well in this area. I found it all easy to clean up even when there has been a spill. The pieces come off easily to be washed by had or if you prefer your dishwasher. This was an important feature to me since I like my coffee to not have that burnt taste you get if its not cleaned well. Ease of Use I would rate this above average. It is very uncomplicated. Its straight forward in the directions which you probably don't need. Its simple and easy to do. My grandchildren use it to make water for hot chocolate and tea and they can even do it with supervision of course. Design This I would rate above average just based on the fact that I love love love the design. It simple and sophisticated all in one unit. I feel like it has a modern feel to it also which I enjoy. Durability Its very durable. We have moved several times and it has survived with out any problems. First to be unpacked. It has continued to give wonderful coffee since the first day we got it. It continues to be a very dependable coffee maker.
