The main trade-off
The K-Duo Gen 2 expressly supports K-Cup pods and grounds, while the CM371 is presented for ground coffee and lists both Over Ice and Cold Brew modes.
Quick verdict
If you rely on K-Cups, the K-Duo Gen 2 is the clearly documented fit: Keurig says it brews pods or grounds. If you mainly use grounds and want a brewer whose CM371 page names a separate Cold Brew mode, the Ninja is the better documented fit for that preference. The product pages do not establish a taste or speed winner.
Choose Ninja Hot & Iced XL Coffee Maker CM371 if
- You use ground coffee and want the CM371's listed Cold Brew mode in addition to Over Ice.
Choose Keurig K-Duo Hot & Iced Gen 2 if
- K-Cup pods are part of your routine.
When the recommendation changes
- If using K-Cups is essential, the K-Duo's documented pod support decides the choice.
- If a dedicated Cold Brew control is essential, verify the K-Duo's exact guide first; the Keurig product page reviewed here confirms Brew Over Ice but does not settle whether a separate Cold Brew mode is available.
The differences that matter
| Decision point | Ninja Hot & Iced XL Coffee Maker CM371 | Keurig K-Duo Hot & Iced Gen 2 |
|---|---|---|
| Brew Input And Pod Ecosystem | Ground coffee with a permanent filter; SharkNinja Product Expert says CM371 does not take K-Cups.[1, 3] | K-Cup pods or ground coffee.[2] |
What this changes: K-Cup users have an explicit pod-compatible option in the K-Duo; grounds-only buyers can choose by other controls.[3, 2] The better fit depends on your priorities | ||
| Iced And Cold Drink Workflow | Over Ice and Cold Brew are listed as separate styles; manufacturer describes Rapid Cold Brew as taking as little as 10 minutes.[1] | Brew Over Ice is listed for a single cup with automatic temperature adjustment; a separate Cold Brew mode is not established by the page reviewed.[2] |
What this changes: The buyer may select by the specific named workflow, while keeping taste and comparative speed unknown.[1, 2] The better fit depends on your priorities | ||
Best for your routine
A household that wants K-Cups and grounds in the same brewer.
Best fit: Keurig K-Duo Hot & Iced Gen 2
Based on listed features, not comparative testing.
Keurig explicitly lists both K-Cup pods and ground coffee for the K-Duo Gen 2. The CM371 Q&A answer from SharkNinja Product Expert says that model does not take K-Cups.
A buyer whose choice depends on whether the selected Keurig model has a separately named Cold Brew mode.
The better fit depends on your priorities
The CM371 page lists a separate Cold Brew mode, while the Keurig page reviewed confirms Brew Over Ice but does not resolve whether this model also has a separate Cold Brew mode. Verify the exact Keurig guide if that is decisive; the page omission is not proof that the mode is absent.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
If one costs more when you shop, decide whether its documented coffee-input and drink controls fit your routine; this comparison does not identify a price winner.
There isn’t enough price history here to tell whether now is a good time to buy.
Limitations
- The listed controls are manufacturer-described features, not a comparative taste, temperature, extraction, or speed test.
- The SharkNinja 'as little as 10 minutes' Cold Brew statement is a manufacturer claim, not a measured comparison against the K-Duo.
- Keurig's product page confirms Brew Over Ice but does not establish whether the K-Duo Gen 2 also has a separate Cold Brew mode; check the exact guide if that feature is decisive.
Questions shoppers ask
Does the Ninja CM371 take K-Cups?
No. A SharkNinja Product Expert answered that the CM371 does not take K-Cups. Keurig explicitly says the K-Duo Gen 2 accepts K-Cup pods or ground coffee.
Does Brew Over Ice mean the K-Duo has a Cold Brew mode?
They are separately named controls on the product pages: Keurig describes Brew Over Ice for a single cup, while SharkNinja lists both Over Ice and Cold Brew on the CM371. The Keurig page reviewed here does not answer whether a separate Cold Brew mode is also available on its brewer.
