I get this from China as I know the supplier. It is said to be with Korean firmware and produced in China.
OScam works fine with me. Netflix HD no, from what I read though all the forums, seems not so easy to get Netflix HD except with Roku/Amazon boxes.
I have no issues with scanning for Terrestrial, Sat or Cable. But some 4k satellite channels are crappy with broken images. For example, 10727 on Hotbird.
Kodi is working but not for 4k playback. Most add-ons are fine. I did not test a lot as I only use a few like 1channel and genesis.
