Ninja SLUSHi Professional Frozen Drink Maker, 88 oz, 2 Preset Programs, Teal, FS299 Review (2026)
Updated September 21, 2026 · Research-based review
Our verdict
The Ninja SLUSHi FS299 suits patio and party setups that want the brand's largest 88oz frozen drink vessel without paying for the higher end preset count. Its self chilling RapidChill design skips watered down ice, but only two presets mean less texture control than Ninja's pricier SLUSHi models.

What we liked
- + 88 oz vessel gives the same large batch size as the top model
- + Teal color adds a fun look to a patio or party bar setup
- + Self-chilling design makes frozen drinks without watered-down ice
Trade-offs
- - Only 2 presets, so texture control is more limited
- - Bright color may not suit every kitchen or bar style
Full size vessel, exclusive color
The FS299 uses the same 88oz vessel size as Ninja's top tier SLUSHi model, with a 64oz maximum fill line, making it a full size machine rather than the smaller 72oz version in the lineup. It is finished in a teal color that is sold exclusively through Amazon, distinguishing it visually from the black and blue finishes used on other SLUSHi models at different price points. For anyone specifically wanting the largest batch size Ninja offers in this product line, the FS299 matches that capacity while sitting in the middle of the lineup on price.
RapidChill self chilling technology
Rather than relying on added ice, which dilutes a drink as it melts, the machine uses RapidChill technology, a two part system that spins an auger around a cooling cylinder to freeze the liquid mixture evenly from within the machine itself. That self chilling approach is the core feature across the whole SLUSHi lineup, and it means a batch goes from room temperature liquid to a frozen, slush like texture without needing bagged ice added at any point. The result is a drink that is not watered down the way a traditional blended, ice based frozen drink can be after sitting for a few minutes.
Two presets: Slush and Frozen Drink
The FS299 includes two preset programs, labeled Slush and Frozen Drink, compared to the three presets on the mid tier FS300 and five presets on the higher end FS301. Each preset targets a different finished texture suited to different serves, a looser slush style pour versus a thicker, frozen margarita style drink. Buyers can still adjust texture manually within either preset to land somewhere in between, but the FS299 does not offer the wider range of dedicated one touch settings found on the pricier models in the lineup, which is the main functional trade off for its lower price and position in the range.
Alcohol limit and manual alerts
The FS299 is rated for mixtures up to 16 percent alcohol by volume, lower than the 20 percent ceiling on Ninja's higher end SLUSHi Max models, which matters for anyone building stronger frozen cocktails rather than lighter spritz style drinks. It also relies on manual, flashing light alerts to signal when a batch is ready, rather than the smart text style status alerts built into the top tier models. Neither limitation prevents the machine from doing its core job well, but both are worth knowing for buyers comparing it directly against Ninja's more expensive SLUSHi options before assuming feature parity.
Where the FS299 fits
For a patio bar, pool party, or backyard entertaining setup that wants Ninja's largest 88oz batch size without paying for the full five preset, smart alert feature set of the flagship model, the FS299 is a reasonable middle ground. It suits hosts who are comfortable using manual controls to fine tune texture rather than relying entirely on presets. Anyone who wants maximum preset variety, a higher alcohol ceiling, or smart status alerts should look at the higher tier SLUSHi models instead, while anyone who just wants large batch frozen drinks without extra features gets solid value here. The exclusive teal finish also gives it a distinct look next to the darker colorways sold on Ninja's other SLUSHi machines.
