Ninja SLUSHi Frozen Drink Maker Review: Would Owners Buy It Again?
Disclosure: As an Amazon Associate I earn from qualifying purchases. If you buy through links on this page we may earn a commission at no extra cost to you. How this review was made: We did not test this machine in person. This verdict is based on our analysis of expert reviews, retailer review summaries and owner reports, all listed at the end of this article. The machine is fairly new, so multi-year durability data is limited, and we say so below. Our method.
A genuine slush machine for families who will use it often
The SLUSHi has its own cooling system, so you pour in a chilled liquid and get real slush in roughly 15 to 25 minutes without freezing anything first. Testers found it easy to run and quieter than a blender. Against that, it is tall and heavy, cleaning the spout and tap can be fiddly, drinks need enough sugar to freeze properly, and leaks are the top complaint in one analysis of owner reviews. It suits households that love frozen drinks and have counter space; occasional users may find it more machine than they need.

- make slushies, frozen coffee or milkshakes often
- host family gatherings and want drinks on tap
- want frozen drinks without pre-freezing a bowl or pint
Skip it if you…
- have little counter or under-cabinet space
- want sugar-free or very low-calorie frozen drinks
- want a quick, low-effort cleanup every time
The Ninja SLUSHi is a countertop frozen drink machine with a built-in cooling system. You pour a chilled liquid into the vessel, pick a preset such as slush, frozen juice, frappe or milkshake, and an auger churns it until it turns to slush. A pull handle dispenses the drink.
We focused on its everyday uses: fruit slushies, frozen coffee, frozen juices and milkshakes. We looked at expert tests and owner feedback, and flag where long-term evidence is still thin.

How it holds up over time
The SLUSHi has not been on sale long enough for solid multi-year data. Reports so far point to early leaks and occasional units that will not freeze, which Ninja has handled under its warranty in the cases we found. Following the fill limits and sugar guidance avoids many of the "it stayed liquid" complaints.
Tips from owners
- Chill the liquid first to shorten the wait.
- Check the sugar level, since diet drinks will not freeze into slush.
- Stay within the fill lines; overfilling was behind at least one watery result.
- Run the rinse cycle right away and use a small brush around the tap.
- Measure your cabinet height before buying.

Frequently asked questions
Do I need to freeze anything first?
No. The machine cools the liquid itself, unlike the CREAMi, which needs a base frozen for about a day.
How long does a batch take?
TechRadar measured about 15 minutes for frozen juice and up to about 25 minutes for frozen coffee.
Can it make sugar-free slushies?
Not reliably. Drinks need a minimum sugar level, so diet sodas tend to stay liquid.
Is it loud?
Testers describe it as quieter than a blender, at about 55 dB in TechRadar's test.
What if it leaks or won't freeze?
Contact Ninja; in reports we found, defective units were replaced under its warranty.
