I've used one of these for the last two years. the only problem I have had
is on reboot it would try to change to the last channel by entering the
numbers X4. (channel 123 was 111122223333) But this has only happened twice
once I rebooted the other time I unplugged and re-plugged it in. Both times
it solved the problem. Other than that it has worked fine.
