This brewer makes enough concentrate for a week's worth of drinks that taste even better than the ones in the specialty stores. After all, they're a lot less expensive. I have to limit myself to one or two a day. I use skim milk, vanilla, and stevia to flavor mine and get a delicious, healthy. low-calorie drink. Check the calories and fat in the commercial ones! I read all reviews before buying, which say follow the printed directions. I'm more than satisfied. I'm delighted. [This review was collected as part of a promotion.]
