The Ninja Slushi vs COWSAR choice is about $110 on Amazon: the Ninja listed at $299.00 and the COWSAR at $189.10 on October 16, 2026, and both freeze drinks without ice using a built-in compressor.
I tested the COWSAR with plain pineapple juice in my COWSAR frozen drink machine review. For the Ninja, I rely on Bob Diff, a YouTube reviewer who paid $300 for his unit and tested it with a family of nine, who found it turns nearly any sweet drink into slush.
