Your guess was spot on. Amazon, and youpost.
I think it is really good, and currently use it as a set top box only so have the 16GB version.
If you want to use it as a plex server then I think the 500GB version is better suited with media stored on network for medium to large libraries.
I got it with a remote and a single controller as a package.
For media I use Netflix, Plex (client) and Kodi. All my medfia is either cloud based or on my linux file server/plex server.
It starts up the TV when it switches on from standby and when the TV turns off it returns to standby something most of my previous set top boxes failed to do successfully.
I actually like to box, previously I have had minux and zidoo boxes that have each lasted around 18 months before needing to be replaced to keep up with tech advances
