Tips for Best Results:
- For best results, use the blender in a tall, narrow container.
- When blending hot liquids, allow them to cool slightly before blending to prevent pressure buildup and potential burns.
- Do not overfill the blending container. Leave enough space for the ingredients to move freely.
- Avoid operating the blender continuously for more than one minute to prevent overheating. Allow it to rest between uses.
