I've used the same one at home for over five years.  It makes 3-5 cups of coffee EVERY day.  It works great and makes a great cup of coffee.  Three years ago, I bought another and took it into the office.  Same experience, altho this one doesn't get as much use. I bought two more to backup my home and office coffeemakers, but I'm not sure whether I'll ever need them.  Maybe I'll make them stocking stuffers for one of the kids.
