I love this cold brewer. I'm on a refined sugar-free diet so I can't have regular coffee creamers. I switched to cold-brewed coffee as it doesn't burn the beans in the brewing process and leave you with a bitter taste like regular brewed coffee, that way I don't need to overload this coffee with a sugar-filled creamer to make it bearable. 
I fill 1/4 of my cup up with the cold brew and the rest with ice, sugar-free, non-dairy creamer, + 1 scoop of collagen. Delicious!
 It's so easy to clean and stores in the fridge with easy access. The spout does not leak which is pretty awesome too.  Highly recommend if you are considering a cold brew coffee maker.
