Promising review: "This coffee maker is my BEST FRIEND! I use this every day, it's so easy to use! My coffee comes out perfect every time. I'm a cold coffee drinker and I put about 8-10 scoops of freshly ground coffee into the filter. I let it sit overnight and the next morning, I remove the filter and dump the grounds. It makes four days; worth of coffee and I love that it's ready to go for me, especially since I wake up at 4:50 am and I need to make my coffee quickly! It's very easy to clean as well. Make sure to remove the rubber linings inside the caps so that you can clean in the crevices. I would recommend rinsing the filter thoroughly as soon as you remove the coffee grounds. If you don't, the gentle filter will begin to 'stain' and be hard to wash by hand. If that happens, just throw it in the dishwasher and it comes out good as new!" —Panda
