Does the battery come in the box?

No. The blender is sold as a bare tool in the KitchenAid Go cordless line, so you need a KitchenAid Go battery and charger, which are sold separately. Check that you already own one or budget for it.

It lists an ice crusher feature, but with one speed and a small motor it works best on a few cubes or crushed ice. Large or frozen-solid cubes may stall it or leave chunks.

How does it compare with a corded personal blender?

A corded blender of similar size gives more power and usually a lower total outlay. The Go wins on portability and on sharing batteries with other KitchenAid Go tools.

Can I use it for hot liquids?

No. It is designed for cold blends like smoothies and shakes. Hot liquid builds pressure in a sealed jar and can be dangerous.

Is the jar dishwasher safe?

The jar and lid are best rinsed promptly and washed by hand or on a dishwasher's top rack. Remove the blade assembly first and check the manual for the exact guidance.
