Ninja SLUSHi FS299 vs FS301: Which Frozen Drink Maker Is Worth Buying?

A few weeks ago, I got my hands on two of Ninja’s most talked-about frozen drink makers — the Ninja SLUSHi FS299 and FS301. Both claim to turn your favorite beverages into smooth, restaurant-quality slushies without the need for ice. I’m a sucker for cold, refreshing drinks, so I decided to put these machines to the test in my own kitchen. After several rounds of iced coffees, frozen margaritas, and even some fruit juice experiments, I discovered that while they look quite similar, there are key differences that actually affect performance, convenience, and versatility.

If you’re torn between the FS299 and FS301, let me walk you through what sets them apart and which one might be the better fit for your countertop.

Key Difference Between Ninja SLUSHi FS299 vs FS301 Frozen Drink Maker

The main difference between the Ninja SLUSHi FS299 and FS301 lies in the number of preset programs and the level of control each model offers. The FS299 comes with 2 preset settings, while the FS301 includes 5 presets, giving you more flexibility when making a variety of frozen drinks. The FS301 also adds enhanced texture control, allowing you to fine-tune the consistency from thicker to thinner slush, something that truly elevates your experience.

Both models use Ninja’s RapidChill Technology and the same 88-ounce vessel, but the FS301 offers a more premium feel with expanded functionality — perfect for those who love experimenting with different types of drinks.

Detailed Comparative Review

Before diving into the finer details, I spent some quality time testing both models to see how they actually perform in a real kitchen setup. From blending morning smoothies to making chilled weekend margaritas, I pushed each slushie maker to its limits. What follows is my firsthand experience comparing their design, usability, performance, and overall value — so you can decide which model truly deserves a spot on your countertop.

Design & Build Quality

At first glance, both models look strikingly similar. They share the same tall, sleek profile with a clear vessel that shows your drink slowly transforming into an icy masterpiece. The FS299 comes in a teal finish that adds a pop of color to the kitchen, while the FS301 has a more sophisticated black design with premium accents.

The FS301 does feel a bit sturdier overall. Its control dial has a smoother, more tactile turn, and the overall build feels slightly more refined. Both have detachable drip trays and removable lids, which make cleanup easy. But if aesthetics matter to you, I’d say the FS301 wins for its professional look.

Ease of Use

Here’s where both models shine. You literally pour in your liquid, choose your preset, and let the machine do the work. The FS299, with its two preset programs, is perfect for quick results — ideal if you just want a frozen drink or slush without fiddling with extra settings.

On the other hand, the FS301 gives you more control. It has five presets, including options for margaritas, frappés, frozen coffee, and more. I personally enjoyed this flexibility because it allowed me to fine-tune the consistency depending on the drink. For example, I could make my frappés smoother and my margaritas icier.

Both models can take anywhere from 15 to 60 minutes to complete the slushing process, depending on ingredients and quantity. And yes, you’ll need to include sugar (or a sugar substitute) for the best texture. The FS301’s temperature control dial felt more responsive, letting me achieve that perfect slush faster.

Performance & Functions

Performance-wise, both are powered by Ninja’s RapidChill Technology, which freezes liquids evenly without the need for ice. This is a game-changer — no more watered-down drinks! The auger inside spins around the cooling cylinder, ensuring even freezing and maintaining a consistent texture.

However, the FS301 clearly performs better in versatility. With 5 presets, it’s like having a mini frozen drink lab at home. I tried making iced lattes, strawberry slushies, and even frozen sangria — all came out great. The FS299, while solid, felt a bit limited since you have to rely on its 2 general presets.

In terms of consistency, both delivered smooth results. But the FS301 maintained the slush temperature longer and seemed slightly more efficient at preventing over-freezing. Plus, it kept drinks frozen for up to 12 hours, thanks to its WhisperChill compressor that works quietly in the background.

Cleaning & Maintenance

No one likes cleanup after a fun drink session, but Ninja made it easy. Both machines have dishwasher-safe parts, including the vessel, lid, and drip tray. I noticed that residue builds up a bit faster in the FS299’s spout area, but nothing major. The FS301’s detachable design and smooth inner surface made cleaning noticeably easier.

If you often host gatherings or plan to use your slushie maker frequently, the FS301’s cleanup convenience is definitely worth the upgrade.

Noise Level

Both models feature Ninja’s WhisperChill Compressor, and they’re impressively quiet for what they do. The FS299 emits a soft hum, while the FS301 is even quieter — something you’ll appreciate if you’re entertaining guests or making a late-night drink.

Conclusion and My Recommendation

After testing both, here’s my honest take — if you’re looking for a simple, budget-friendly frozen drink maker for occasional use, the Ninja SLUSHi FS299 is more than enough. It delivers great results with minimal effort and looks charming in teal.

However, if you’re someone who enjoys experimenting with different beverages — from margaritas to frappés and beyond — the Ninja SLUSHi FS301 is worth the extra investment. The five presets, better texture control, and upgraded design make it feel more professional and capable.

In my kitchen, the FS301 became the go-to for every gathering and weekend treat. It’s simply the more complete machine of the two — powerful, quiet, and consistently reliable.

Final Verdict:
If versatility and control matter most, go for the FS301. But if you just want frozen fun on a budget, the FS299 will still make your drinks shine.
