Which makes me reiterate the point that my s912 android box is way more responsive then my buzz 3000 with a 905x chip on it. The buzzbox has a buzz livetv middleware on it but that can be achieved with a stb eumlator. The fact is That i do own a buzz 3000 and use it daily with vader streams and it works good but the apps run slow on it.
I just give my opinion and people can take it with a grain of salt.
I recently used OK2 on a s912 Android box with STB Emu and it was fast and snappy. The s912 however did come out after the s905x. But prefer a dedicated software over the STB Emu. Sometimes there are STB Emu updates that have bugs and you have to uninstall and install the previous version or wait for an update.
