The 2ltr jug is most versatile as it is suited for both drinks and grinding dry ingredients, and for blending foods (because of the narrow base) like spreads, hummus, nut butter and pesto. It is light-weight, and easy to clean. The blades are removable and replaceable. The 2ltr jug doesn’t fit in the sound cover. Opt for the 1.5 litre narrow base model for the same functionality with the optional use of a sound cover.
