Ninja Coffee Brewer is so easy to use. I love that the water reservoir comes off to fill up. The Ninja Coffee Brewer comes with a handy coffee measuring scoop for easy measurements, 1 scoop per cup. It also comes with a reusable gold filter that works well or you can buy cone filters if preferred. The coffee brewer is easy to set for delayed brewing and I love that I can keep the warmer on for up to 4 hours instead of the standard 2 hours. The coffee taste great (even though I used less than the 1 to 1 ratio) and it is easy to rinse and clean.
