Love the product, B70, when it works. Love the choice of coffees and the design. The problem is the unit keeps cutting off for no reason, meaning each time we'd like coffee, we have to wait for the unit to essentially reboot. Also, the amount of coffee portioned out seems to vary even when using the same setting. Took it back and heard many others are having the same problem with the unit shutting off. Too bad. I'm going to give the second unit a chance because we like the concept...but the unit must be reliable. We'll look for other options if this one also fails. Keurig is missing a grand brand-building opportunity, given they own the market. Quality control seems to be an issue.Keurig B70 Gourmet Single-Cup Home Brewing System
