## What reviewers say

**Ninja Professional Plus Blender with Auto-iQ (BN701)** — Only one whitelisted tester—Tom's Guide—hands-on reviewed this exact BN701 (its deal blocks explicitly list it as the 'Ninja BN701 Professional Plus Blender'). It rates smoothies, oat-milk milling and ice-crushing near premium Vitamix/Breville levels at under-$100 value, but flags punishing loudness (measured 94.9 dB), cheap-feeling materials and a fiddly stacked-blade assembly that is tricky to clean. (1 sourced review.)

**KitchenAid K400 Variable Speed Blender** — Both whitelisted reviewers tested the K400 hands-on. They agree on the sturdy die-cast metal base, the wide range of color options, and a smooth, glossy result on an emulsified dip (Tom's Guide's hummus, TechRadar's mayo). They diverge sharply on smoothies and value: TechRadar (2021) rated it a strong all-round performer with silky, bit-free smoothies, while Tom's Guide (2025) got a gritty smoothie and judged it overpriced next to a cheaper Ninja. TechRadar separately flagged uneven hazelnut blending. (2 sourced reviews.)
