I recently got my hands on two Ninja SLUSHi machines, the FS299 and FS301, both designed to transform ordinary beverages into icy, flavorful treats without the need for ice. Having tested both extensively, I was curious about how the differences in preset programs, capacity, and controls affect the frozen drink experience. After experimenting with everything from margaritas to sugar-free slushies, here’s a detailed comparison based on real use.
Key Difference Between Ninja Slushie FS299 vs FS301 Frozen Drink Machine
The main difference between the FS299 and FS301 lies in the number of preset programs and the level of customization. The FS301 offers 5 preset programs, while the FS299 provides only 2. This makes the FS301 more versatile for a variety of drinks, including frappés and creative frozen concoctions. Both machines have the same 88 oz vessel and RapidChill Technology, so the core freezing performance is nearly identical, but FS301 offers greater flexibility and options for customization.

Detailed Comparative Review
Design
The FS299 comes in a striking teal finish with premium accents, giving it a fun, modern look for any kitchen or bar setup. Its 88 oz vessel is large enough to serve multiple guests at once, and the detachable lid and drip tray make it easy to handle.
The FS301, in black, has a slightly more sophisticated look, featuring a premium dial for preset selections. Both machines feel sturdy and well-built, but the FS301’s aesthetic and tactile controls provide a slightly more refined user experience.

Ease of Use
Operating both machines is intuitive.
- FS299: With its 2 preset programs, the FS299 is straightforward—simply pour your liquid, select a program, and let the machine do the rest. It handles standard frozen drinks like margaritas or iced coffee effortlessly.
- FS301: The 5 preset programs provide more variety, allowing me to make not just margaritas but also frappés, smoothies, and other frozen beverages without guesswork. The temperature and texture control lets me customize each drink’s consistency, whether I prefer a thick slush or a softer, more pourable texture.
Both machines require sugar or recommended sugar substitutes for optimal slush consistency, particularly for sugar-free recipes. I found the FS301 slightly easier for experimenting with creative recipes due to the extra programs.

Functions and Performance
Both the FS299 and FS301 leverage RapidChill Technology, which spins an auger around a cooling cylinder to freeze liquids evenly without ice.
- FS299: Performs excellently for standard drinks. Frozen margaritas and iced coffee came out smooth and consistent. Drinks stay frozen for up to 12 hours, thanks to the WhisperChill compressor.
- FS301: Offers the same core technology but with added flexibility thanks to 5 preset programs and customizable settings. I was able to make thicker frappés and fruit-based smoothies that the FS299 handled less effectively due to the limited presets.

Cleaning & Maintenance
Cleaning both machines is a breeze. Dishwasher-safe parts, detachable lids, and drip trays make post-use cleanup fast and simple. Both machines maintain hygiene efficiently and are easy to refill, pour, and store.
Noise and Storage
The WhisperChill compressor in both models keeps noise levels low. I noticed no significant difference in noise, though the FS301 feels slightly more substantial due to its added controls. Both have similar footprints and are easy to store on countertops, though the FS301 may take up a touch more space because of its premium dial and design features.
