Have an identical 2-he bought and set since the rough everyday Ausseinsatz already 3 years ago. The Ausseneinhaiten are still handsome and absolutely tight, even from the constant sunlight nothing is noted, all plastic parts are still OK and even the hinged lid have survived everything without complaint. The teaching of new outlets on the old transmitter or vice versa is very easy, only the somewhat small screws on the DIP switch cover one might criticize. Product in my opinion is highly recommended !!
