No. The compressor chills the liquid directly, so you pour in your mix and the machine freezes it. Drinks aren't watered down by melting ice.

How many servings does one batch make?

The vessel holds 64 oz of liquid, which works out to about seven 9-oz servings. The vessel itself is 88 oz, so there is headroom for expansion as the mix freezes.

How long does the slush stay frozen?

Ninja says slush stays fresh for 12+ hours on recipes without dairy. Dairy-based drinks soften sooner, so plan to serve those first.

Can I make frozen cocktails in it?

Yes. It handles alcoholic and non-alcoholic mixes, though high-proof alcohol freezes more slowly, so expect a longer cycle and use a colder starting mix.

A built-in rinse cycle clears leftover slush in seconds. The vessel and auger still come apart for hand washing, and the base wipes clean.

How does it compare with a blender slush maker?

A blender crushes ice in batches and can water down the drink. This machine freezes the mix itself and holds it frozen, at the cost of counter space and a longer first-batch wait.
