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