ZGemma H11S 4K UHD Satellite receiver. Latest model. Purchased 6 weeks ago because I thought our Humax box was knackered. Turns out it just wasn't talking to the Tele properly.

Comes with power supply, remote, and a memory stick loaded with Open ATV 6.4 (plug it in the back). You can load different operating systems or "images" then "flash" the box . It does many many things if you're good with tech. There's loads of information online. I just watched Freesat on it.

The instruction manual comes up very quickly with a Google search.
