I bought this to replace a Breville Grind Control that began to regularly overflow coffee grounds and I had high hopes but am really only feeling meh about this machine. The capacity is less than the Breville and that means either one of us gets shorted on our to-go cup, or we have to brew an additional single cup. The thermal carafe does not retain heat well at all.  Coffee quickly cools to lukewarm. Lastly, the water container often leaks from the bottom, and that seems like it should be a simple design fix for Ninja to upgrade the seal so the fit is better and prevents the leaks. On the upside, it's super easy to clean, especially compared to the Breville, and both tea and coffee brew nicely.
