What the evidence shows

The Ninja Thirsti Ultimate Drink System introduces notable improvements over its predecessor, primarily in operational speed. Reviewer testing confirms it dispenses drinks in about half the time of the original model. This Ultimate version also supports a new, larger flavor pod size that is formulated with real sugar.

The Ninja Thirsti Ultimate Drink System is a faster, redesigned offering, clearly outperforming the original in drink preparation speed as verified by independent review. Its introduction of a new, larger real-sugar flavor pod system is another key differentiator, catering to users who appreciate proprietary flavor options. However, consumers should consider its higher price point and the confirmed limitation to 12 oz and 24 oz drink sizes. While the original offered avenues for custom CO2 and flavorings via modifications, the Ultimate's adaptability in this regard is not yet established, which may influence power users.

Buyer questions answered

Is the Ninja Thirsti Ultimate faster than the original model?

The reviewer conducted side-by-side speed tests, finding that the Ultimate took 38 seconds for a 12 oz drink compared to the original's 1 minute 16 seconds. For a 24 oz drink, the Ultimate finished in 1 minute 14 seconds, while the original took 2 minutes 30 seconds. This demonstrates a substantial speed improvement with the Ultimate.

Can I use my own CO2 tanks or flavorings with the Ninja Thirsti?

The reviewer successfully modified her original Ninja Thirsti to use a standard 5-lb CO2 tank, which is much cheaper to refill than proprietary canisters. She also refills her own flavor pods with options like Kool-Aid, stating they taste better and are more cost-effective than Ninja's offerings. These modifications require a separate cord for CO2 and refilling empty pods, and a hole needs to be drilled in the original machine's door for the CO2 tube.

What are the available drink sizes on the Ninja Thirsti Ultimate?

Unlike the original model which offered 6, 12, 18, and 24 oz sizes, the Ultimate streamlined its options to just 12 oz and 24 oz. The reviewer notes that 6 oz was often too small and 18 oz was awkward, suggesting these changes might align with common user preferences.

Is the Ninja Thirsti Ultimate worth the price increase over the original?

The Ultimate is priced at $179, while the original can be found for $100-$150. The reviewer suggests buyers consider if the significant speed increase and the ability to use Ninja's new larger, real-sugar flavor pods (which are incompatible with the original) justify the higher cost. She personally would only upgrade if her modified original machine breaks.

Does the Ninja Thirsti Ultimate support new flavor pods?

The Ultimate features a redesigned pod slot to accommodate new, larger Ninja flavor pods that offer real sugar soda options. This is a key difference, as these larger pods are incompatible with the original Thirsti machine. This caters to consumers who prefer real sugar over artificial sweeteners.
