I have the items in the following applications running:
** Heating control of electric heaters in the hobby room (since KW45-2013)
** Temperature control Bodenheizmatte in the doghouse (since KW46-2013)
Positives:
Switching capacity 30A -> relay is integrated thus no additional component is necessary
Temperature sensor is included
Easy installation, connections are easily vertändlich
Negatives:
No manual / documentation
The long-term trial runs ;-)
