Overview
Not a full-size pitcher blender, this KOIOS is a personal blender with a motor base, stainless steel blade assemblies and to-go cups that double as drinking bottles. A grinder attachment handles coffee and spices.
Blending straight into the cup saves washing a pitcher, and the grinder attachment adds coffee and spice duty. The cup size limits batches to single servings, and the control is one-touch with no variable speed.
Who it's for
Students, commuters and gym-goers who blend one serving at a time get a cup that goes with them. Families making soups or party batches need a larger pitcher blender.
Pros and cons
- Two to-go cups included
- Grinder attachment for coffee and spices
- BPA free and PVC free
- Cleaning brush included
- Single speed only
- Plastic body material
- Cup material details conflict
Performance notes
The motor spins the blade assembly directly in the cup, so the contents are pulled down toward the blade and blended in short bursts when you hold or pulse. Liquid should go in first and the cup should stay below the fill line. A removable blade makes cleaning easier, and the grinder attachment works on dry ingredients.
