The unit would have been more than televisions in use at me. I also do not expect luxury - but a switching time of 7 seconds (measured, not felt) from one to the next program I found very very very long time. Nor can it be at reception - I have good DVB-T reception and my little TV from X4-Tech has never had any problems and switched quickly.
The service is ok - not quite as easy as I know it from other devices here. But too much I have not done since I was so shocked. The image quality is sufficient. Too bad.
