I received the KitchenAid Cold Brew Coffee Maker and haven't stopped using it since I took it out of the box.  It makes approximately 12 servings of coffee each time you use it.  Keep in mind this depends on your serving size. You may get a few servings more or less. It is so easy to set up and I love the compact size.  It fits nicely in my fridge and doesn't take up too much space.  I try to clean it after every use so everything keeps working properly.  I have been using it for a few weeks and haven't had any trouble with it leaking.  Very pleased with it!
