Diamond pitcher geometry produces a tight vortex for smooth blends
Intelli-Speed sensor keeps RPM steady under heavy loads
Soft start prevents splashing during initial pulses
Metal drive coupling resists wear from daily use
✕ What we don't
Pitcher height does not clear standard upper cabinets
No included travel cups or single-serve accessories
The bottom line The KitchenAid KSB1325ER 5-Speed Diamond Blender claims smoother blends through its Diamond pitcher geometry that creates a directional vortex. Across ten weeks of soups, smoothies, and frozen drinks, the Intelli-Speed sensor maintained consistent RPM under load and the soft start prevented splashing on dense mixes. The metal drive coupling held up to daily use with no slipping. The trade is the 60 oz pitcher which is taller than some cabinets and the limited preset count.
