The Ninja Thirsti system delivers delicious carbonated drinks with easy operation, but its high ongoing cost and significant difficulty in sourcing replacement flavor pods and CO2 canisters make it a challenging purchase.

What the evidence shows
The Ninja Thirsti system allows users to create flavored carbonated drinks by loading flavor pods and selecting a sparkle level. Reviewer experience indicates that a CO2 canister lasts approximately six weeks with daily, multiple-time-a-day use. The system is praised for producing delicious, great-tasting drinks.
While the Ninja Thirsti effectively delivers on its core promise of making good-tasting carbonated beverages with a user-friendly process, the practicalities of its ownership present considerable challenges. The primary obstacle is the poor availability of essential consumables—flavor pods and CO2 canisters—which reviewers found consistently difficult to acquire. This logistical hurdle, coupled with a relatively high per-drink cost, undermines the overall value proposition. Despite its enjoyable output, these ongoing operational frustrations suggest potential buyers should weigh the taste benefits against the sustained effort and expense required to maintain the system.

Buyer questions answered
How does the Ninja Thirsti system work?
The reviewer demonstrates that the Ninja Thirsti requires users to load flavor pods into the machine. They can then select a sparkle level (e.g., level one) and the desired drink size, and the machine dispenses the flavored, carbonated beverage.
How long does a Ninja Thirsti CO2 canister last with regular use?
The reviewer, who used the Ninja Thirsti daily multiple times a day, found that a CO2 canister lasted about 6 weeks before needing replacement. The device also has an orange indicator light that signals when the CO2 tank is almost empty, estimated to have 10-20 drinks remaining.
Are Ninja Thirsti flavor pods and CO2 canisters easy to find and buy?
Initially, the reviewer could not find replacement flavor pods or CO2 canisters, as they were consistently out of stock on both Ninja Canada's and Ninja US's websites, as well as on Amazon. While his sister-in-law later found flavor pods on Amazon, the widespread and prolonged stock issues caused the reviewer to stop using the machine.
What is the ongoing cost of using the Ninja Thirsti system?
The reviewer calculated the per-drink cost to be roughly one dollar (CAD), excluding tax, based on a flavor pod costing $7.99 for 17 drinks and a CO2 canister costing $39.99 for 100 drinks. This recurring cost was a primary reason for the reviewer to stop using the product, describing it as an 'extra monthly bill.'
Does the Ninja Thirsti make good-tasting carbonated drinks?
Despite his critical view on cost and availability, the reviewer unequivocally states that the Ninja Thirsti produces delicious and fantastic drinks, emphasizing that the device itself works awesome. His decision to stop using it was purely financial, not due to product performance or taste.
