Used and fully working P2897 2017 model.

Unboxed but includes upgraded 2019 style aftermarket Remote, HDMI cable, and UK power supply.

Everything you need to quickly setup and go!

Latest update 9.2.4 installed, and factory reset ready for use.
Apps in picture not pre-installed.

In working condition, with age-related marks from normal use, from the previous owner. None of which affect the performance or usage.
The remote's mic doesn't work, but all buttons and the rest of the functions are still working.

I have tested:
Wi-Fi
Ethernet
Bluetooth
Both USB Ports
Google Play Store is able to install apps
Included remote and paired to Shield
Remote's buttons in Input Viewer app

There are no restrictions on side-loading your own Android apps, so this can easily replace other devices which are imposing rules to block this; making this a great cost-effective alternative, to the more expensive later models.
If you plan to use this for Plex, streaming and IPTV, the difference between this model and the later models is negligible.
