Positives: The ease of installation, the image short switching times.
Negatives: EPG is only for a transmitter at the time, but as for 7 days. Channel overview is therefore not available.
Particularly annoying: you switch on the Dolby Digital output, so only it is transmitted. The sound from the Scart output is then shut down; just the reverse. (There will be no bitstream output at the digital output) A quick change between conditioning and surround sound from the TV is so unfortunately prevented.
Wen switching the soundtrack does not interfere with or who has any surround system, is well served with the Techno Trend.
All in all: The device is roughly equivalent to what you would expect for the price, but nothing more.
