Rare

Used but fully working P2571 2015 Pro model with 500GB

Unboxed but includes upgraded 2019 style aftermarket remote and UK power supply.

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

Still has its original HDD with the Widevine L1 keys intact (confirmed by DRM Info as pictured).

In great condition considering its age.
Has had internal dust cleaned, and has minor age-related marks from normal use.
The remote's mic doesn't work, but all buttons and the rest of the functions are still working.

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 streaming and IPTV, the difference between this model and the later models is negligible.
