What Owners Say About the Ninja BL660 Professional Blender
4.7★ across 762 customer reviews · Confidence: 100/100 · ~$110
With 762 customer reviews and a 4.7-star rating, the Ninja BL660 is the most-reviewed and highest-rated blender in this comparison by a wide margin. Owners consistently praise its ability to handle daily smoothies, frozen fruit, and ice without complaint — and the value relative to its price comes up in review after review. At a sub-$110 price point, owners say it performs well beyond what the price tag suggests.
The main caveat owners flag is noise: the BL660 is loud at full speed, and a handful of longer-term owners report that gaskets and seals can show wear after heavy daily use over a couple of years.

What Owners Say About the Vitamix E310 Explorian Blender
4.5★ across 41 customer reviews · Confidence: 54/100 · ~$300–$380
The Vitamix E310 carries a 4.5-star rating from 41 customer reviews — a solid score, but drawn from a much smaller pool. Owners who do review it tend to be enthusiastic: they describe ultra-smooth results on tasks that cheaper blenders struggle with, including nut butters, hot soups blended from friction heat, and fibrous greens. Reviewers frequently cite Vitamix's long-standing brand reputation and multi-year warranty as part of why they chose the E310 despite the higher price.
The main caveat owners surface is the 48 oz container — smaller than many competing blenders at this price tier, which frustrates those blending for families or batch-cooking. The significant upfront cost is the other friction point, with several reviewers noting it took time to justify the investment.

Where They Differ
The most obvious difference is price: the Ninja BL660 costs roughly $110, while the Vitamix E310 runs $300–$380 depending on retailer and timing. That's a gap of $190–$270 — enough to buy a second Ninja with money to spare. For owners blending daily smoothies and the occasional soup, customer reviews on the Ninja suggest it handles those tasks confidently without spending Vitamix money.
Capacity cuts the other way. The Ninja BL660 comes with a 72 oz pitcher; the Vitamix E310 ships with a 48 oz container. Owners blending for three or more people consistently flag this as a real-world constraint on the Vitamix side, while Ninja owners rarely mention capacity as a limitation.
Where Vitamix E310 reviewers pull ahead is on blending thoroughness for more demanding tasks. Owners of the E310 more often mention results on things like smooth nut butters, completely lump-free soups, and green smoothies without leafy texture — categories where raw motor engineering and blade design make a tangible difference. Ninja BL660 owners praise everyday performance but are less vocal about tackling those harder ingredient categories.
Finally, the review volume gap is significant from a confidence standpoint. The Ninja BL660's 762 reviews produce a much more statistically reliable picture of real-world ownership than the Vitamix E310's 41. That doesn't mean the Vitamix is worse — it means there's less customer data to draw from.
How We Compared
The Confidence score combines the star rating with how many people gave it: a product with thousands of reviews and a 4.7 average is harder to argue with than one with 41 reviews at 4.5. The top scorer in each comparison is rescaled to 100, so the scores are relative, not absolute.
Well Seasoned's individual reviews consolidate Amazon customer feedback and YouTube reviewer coverage; this comparison aggregates those reviews. Prices and ratings reflect values recorded at the time of each individual review and may have changed.
