Third-party reviews

What customers like about Kenwood HDM804SI

  • Powerful 1000W motor processes difficult ingredients and thick compounds quickly
  • Triblade system with three angled blades ensures smooth, even blending with fewer lumps
  • Wider blending base diameter efficiently handles large volumes of food in less time
  • Ergonomic Suregrip handle is slim, comfortable, and remains non-slip even when wet
  • Comes with a versatile set of attachments including a chopper, whisk, and milk blender
  • Continuously variable speed dial and a turbo button provide precise blending control
  • Easy to clean as the blending wand and various attachments are dishwasher safe
  • Solid, high-quality metal body construction that resists overheating during extended use

What customers don't like about Kenwood HDM804SI

  • Unit feels somewhat heavy and weighty in the hand compared to plastic alternatives
  • Extra-wide blending guard is too large to fit inside narrower containers like mason jars
  • Metal guard design requires caution to avoid scratching nonstick or enamel cookware
  • Speed dial placement on top makes one-handed adjustments awkward during operation
  • Wide beaker can make it difficult for small-batch recipes like mayonnaise to emulsify
  • Storage is less convenient due to the lack of a dedicated holder for all the extra attachments

Verdict

The Kenwood Triblade System Pro HDM804SI is a premium immersion blender characterized by its high-performance 1000W motor, variable continuous speed control plus a Turbo mode, and a patented Triblade System featuring three multi-angled stainless steel blades housed in an extra-wide 8 cm splash-control foot. It comes well-equipped with useful premium accessories, including a 1-liter graduated beaker with a handle and lid, a 0.5-liter mini chopper, a stainless steel wire balloon whisk, and an emulsifying/foaming tool. Main pros of this silver and grey appliance include its incredible power for handling tough roots or tubers without overheating, a 3.5 cm slim ergonomic handle with Suregrip material for a secure wet-hand grip, and an improved design that offers a 33% larger working surface area to blend food significantly faster. However, notable cons include its relatively substantial total kit weight of 2.57 kg, the lack of a dedicated storage box or stand to organize the multiple loose attachments, and instructions that some users find brief.
