This item is a ScentFluence SMI Flex Pump Box Single scent diffuser. This includes the box part only, I believe that a drum unit is also required to operate this, that is not included. Power supply is included. This came from a tech company that closed.

A powerful easy-to-use atomizing diffuser system. Designed for flexible HVAC installation, with a custom programmable timer and built-in battery.

Shipping and handling will be $25 via USPS Ground Advantage. No local pickup, international shipping only through the eBay Global Shipping Program.
