Ninja SLUSHi FS301: the five questions to answer before buying
It makes frozen drinks without ice, but ingredient rules, cleaning and counter space determine whether it becomes a staple.
Buy the FS301 when frozen drinks are a recurring ritual and you will follow its ingredient guidelines. Skip it when you want occasional slushies but not another large machine to clean and store.

The details that survive checkout.
Ingredients are functional
Sugar and alcohol affect freezing, not just taste. Use Ninja's recipe and ingredient ranges instead of assuming any beverage will slush.
Clean it while it is wet
The rinse cycle is most useful immediately after serving. Letting a sweet drink dry inside turns convenience into a scrubbing job.
It is event-sized
The large vessel makes sense for families and hosting. It is harder to justify when the normal serving is one small drink.
