My husband and I have had this machine for approximately a month now. We have a constant varying in the amount of coffee we need brewed. There are days we want different coffee flavor/brands than the other. Never a problem with any of this. Absolutely in love with the preset modes for travel mugs, and the fact that my large travel mugs that never fit under any machine fit perfectly in this machine. Then when we both are home or have company we can brew a full pot of coffee. All the options for ways to brew and sizes to brew make this machine perfect. Absolutely no complaints. It’s great to see my husband be so excited over a small kitchen appliance.
