The CE251 is Ninja’s entry-level programmable drip machine, built around two brew-strength modes and simple push-button controls rather than a touchscreen or app. TechGearLab put it through lab testing, and its results are the most useful thing available on this machine: solid on temperature, inconsistent on timing, weak on holding heat afterward.
What TechGearLab actually measured
Across five consecutive brews, TechGearLab clocked times ranging from 7:00 to 8:18, averaging 7 minutes 48 seconds — slower than many competitors, and the swing between the fastest and slowest brew suggests the timing is not tightly controlled. On temperature, the average measured 191.6°F, which the reviewers noted falls slightly under the SCA’s preferred range but stays close to it. The warming plate was the weaker result: it lost 10°F over an hour with no active reheating, so coffee left sitting will cool steadily rather than hold steady.
Classic and Rich are close enough that it barely matters
The CE251 offers two brew styles, Classic and Rich, plus a dedicated small-batch mode for under four cups and a sneak-a-cup feature that lets you pour mid-brew without a mess. TechGearLab’s testers described Rich as producing a “slightly stronger” cup than Classic, but called the difference minimal and hard to taste in practice. If you were hoping for a meaningful strength dial, this is closer to a marginal adjustment than two distinct brewing profiles.
Straightforward controls, one awkward layout choice
The interface is dedicated push buttons rather than a menu, which TechGearLab credited as genuinely easy to learn, and the 24-hour programmable auto-brew works as expected for setting coffee up the night before. The removable water tank has grip indents for easier filling, and most parts are dishwasher-safe. The one layout complaint in testing was the water reservoir’s position on the right side of the machine, which the reviewers flagged as awkward specifically for left-handed users refilling it.
What the low price buys you
This is a budget machine, and the test results read like one: temperature performance that is close to good rather than dialed in, a warming plate that does not actually hold heat, and brew times that vary run to run. None of that makes it a bad machine at its price point — the button-based strength control and small-batch mode are real, useful features that pricier machines sometimes skip. It just means you should not expect café-grade consistency from it.
Before you buy
- Plan to drink coffee within the first hour of brewing, or transfer it to an insulated vessel — the warming plate loses heat measurably after that.
- Do not expect a strong taste difference between Classic and Rich modes; treat it as a minor adjustment, not a real strength dial.
- If you are left-handed, check the right-side water tank position in photos before buying — testers specifically flagged it as inconvenient.
- Confirm the small-batch mode threshold (under four cups) matches how you actually brew day to day.
