What reviewers say

Sourced tester consensus for each — the "what people who used it think" layer, not just specs.

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, 1 lab-tested.)

Praised: Smoothies surpassed nearly all blenders tested, bettered only by Vitamix A3500 and Breville 3x Bluicer; Strong milling and ice-crushing power for the price (smooth oat milk, no chunks); Huge value under $100, with secure locking lid, pour spout and grippy handle.

Flagged: Painfully loud, especially in ice-crush mode (measured 94.9 dB); Feels built from lower-quality materials; Stacked blade assembly is fiddly and tricky to clean.

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, 2 lab-tested.)

Praised: Sturdy, weighty die-cast metal base that stays stable at full speed; Smooth, glossy result on an emulsified dip — Tom's Guide's hummus and TechRadar's mayo; Wide range of color options to match a KitchenAid kitchen.

Flagged: Control-dial gripes: small preset symbols (TechRadar) and a wobbly, insecure-feeling knob (Tom's Guide); Uneven hazelnut blending — a mix of powder and larger pieces, with residue stuck under the blades; Premium price feels like paying for the brand versus a cheaper, better-performing Ninja.
