Some of the early AeroPress Go chambers have a problem. The filter cap will not engage when you screw it onto the chamber. Please see the two photos, one with the filter cap not engaged and one with the filter cap engaged. If you have an AeroPress Go that the filter cap and the chamber will not engage, send your request along with your mailing address to info@aeropress.com and we will send you a new chamber. We apologize.
