Third-party reviews

What customers like about Ninja CE251

  • The 1.77 L water tank is removable and easy to fill.
  • A reusable filter comes with the machine, so no paper filters are needed.
  • It brews a full 12-cup pot for several coffee drinkers.
  • It switches itself off after brewing.
  • The coffee is rich and tastes good.
  • It has a solid feel and a modern look.

What customers don't like about Ninja CE251

  • It is tall, so it may not fit under low kitchen cabinets.
  • The glass jug has no cup markings, so measuring a set amount takes guesswork.
  • Coffee can come out stronger than intended, and some drinkers find the finish harsh.
  • The machine gets loud and releases steam at the end of brewing.
  • The glass jug is not insulated, so coffee cools faster than in a steel flask.

Verdict

The 1.77 L water tank is the main reason to look at the Ninja CE251, a machine for a household with several coffee drinkers. The coffee is rich and tastes good, and the brew is quiet for most of the cycle, though it gets louder at the end. A full 12-cup pot takes about 12 to 15 minutes in tests, and the coffee comes out very hot, so handle the jug with care. The water tank comes out easily for filling, and the reusable filter means no paper filters. The trade-off is size: it is tall, so it may not fit under low cabinets, and the glass jug has no cup markings. It suits a family or small office that wants a big pot at once, a simple setup and a machine that feels solid.
