No it's an official Microsoft dongle for the XBOX ONE, if you cannot get it cheap look for others.
Its is not urgent, it is not needed. It is only there to pickup DVB-T/T2 TV (Freeview in the UK) form you Ariel and let you watch it form any connected device (phone etc) but I've forgotten what this project was for.
It does the same as
https://www.raspberrypi.org/products/ra ... pi-tv-hat/ but via USB so takes up more space.
There are other TV dongles you can buy too.
(Background to my usage, most Poundland shops had them in for £5 and have been seen for a bit less online. I was passing so bought one to see if I can use it, I cannot on Windows10 but on the Pi it works nicely. Some irony there.
To see one on Amazon use B00E97HVJI as the search.
Look on eBay etc as propel almost certainly bought a load from Poundland to sell on
A case is a case, they'll both work, no idea which is 'better'.
