product features and I can not say much, Fernbedinung clear optics look good ...
manual I found confusing but probably just because I have no satellite: D
the troubleshooting tips were just not helpful:
"Error 81 U ----- Cause: device does not work ---- Remedy: Switch off the unit, and re-enable"
yes that also did not help ...
had exchanged without problems at Amazon, so can Amazon only recommend everyone, never have until now what to complain about
