What is the purpose of the funnel?Updated a year ago

Use the funnel to transfer the ground coffee from your coffee grinder bin to the AeroPress Original or AeroPress Go chamber. It was not an intended use but users have told us that the funnel fits on the bottom of the chamber and enables you to press into smaller mugs. If you do this, we advise you to make sure you use a sturdy mug and that you firmly hold the mug and AeroPress Go or AeroPress Original chamber during pressing to avoid spilling.
