Overview

As is common with Amazon devices, this "Digital Media Receiver" device was registered with the FCC by an unknown Limited Liability Corporation (L Laury LLC). Its circular label suggests that it may be a new Echo device.


This device was under short-term confidentiality, but that expired 11/26/2019 ⚠.
