my son gave this to me as a gift and I loved the concept. But every single brew.. or k cup I get grounds. We have tried absolutely everything. Grounds and more grounds.

Got it for Christmas. Stopped working all of a sudden. It kept saying there is no water in the tank when the tank is full. Sensor detection error I believe. I returned to Sam's.

I've had my Ninja Dualbrew foe about a year and all I can say is I LOVE IT! Brews super fast and my coffee is perfect every time! I love being able to also heat water for a cup of tea or bowl of hit cereal quickly. Awesome machine!!

This would be the perfect coffee maker if it was a Duo instead of having to switch out the attachment for Pod and ground coffee, other than that this brews coffee perfect with optimal temperature, giving the coffee the best taste.

Never worked right coffee isn't warm. Very hard to use. I was so excited about this product. I will never buy ninja again. When switching it takes several tries for it to work coffe grinds in pot.

It has a lot of gizmos, but the unit is under powered, coffee is not hot in all settings, coffee does not taste good. I miss my old coffee maker, do not waste your money, look else where.

Love my coffee maker. Like the fact that can use ground coffee or pods. Also can do hot water for tea. I owned it for about 6 months and works perfect. Never had any issues with it and use it almost daily.

Ninja is one of the absolute best! We love the fact that it does pods, grounds or specialty brews.. It does brew slower than other name brands but that's ok! It's very user friendly and easy to clean. I definitely would buy again, if needed.

I absolutely love my ninja coffee maker. I can brew one cup or a whole pot that is larger than most coffee pots. It works great and is highly recommended!

Very good coffee system. You can choose between pods or filter. Makes a big or small amount of coffee. You can program the machine and you will have the coffee ready in the morning. Cleaning is a little challenging.
