The Teach done automatically during startup (assuming the connected equipment is there already in standby) Pressing the remote control is always detected without difficulty and switching takes place very quickly. the shutdown is also quite fast (approx 15Sekunden) I am very pleased - about the durability, no statement can be made - the processing also does not look cheap, so I hope to be able to use the device for long.
I'm saving so although only 20, - / year but pays off in any case quickly.
