Questions and answers
- Which is better for crushing ice?
- The Ninja BlendBoss, on paper. Its 1,200-watt motor outpowers the Beast's 850 watts, and Beast buyers note thicker blends sometimes need longer. Both are rated for ice and frozen fruit.
- Is the Beast worth $60 more?
- Only if the stainless steel vessel matters to you. You pay $159 at Macy's versus $99 at eBay for the Ninja, and the extra buys a metal cup, three vessels and a smaller footprint, not more power.
- Which is better for single-serving smoothies?
- The Beast Mighty 850. Its vessels double as drinking cups with a drinking lid, and buyers praise it for single servings. The Ninja includes one 26-oz cup with a flip-top lid and straw.
- Which has a better warranty?
- The Ninja BlendBoss states a 1-year warranty. The Beast listing does not state one, so confirm coverage with the store before buying.
- Can either handle large batches?
- Neither is a full-size pitcher blender. Both use 26-oz-class vessels, and Beast buyers complain the cups are too small for larger batches.
- Which is more reliable based on ratings?
- The Ninja has far more feedback: 4.6 from 422 ratings versus 4.5 from 27. The larger sample is the safer signal, though neither rating shows a pattern of failures.
