Best quality and value controller on Amazon
Best quality and value controller on Amazon. Very easy to configure. Used several for 2 years now ( in outdoor covered location ). No failures. Very reliable. And if you're handy with a soldering iron, you can easily modify these to be solid state for higher frequency switching and even higher reliability. Excellent !Update Nov 23 : been running several of these for nearly two years with frequent switching. No problems at all.

Works well
Am using this item as a spare controller and is not in current use. Made it up with other components and tested for a week in use and found it quite reliable

Does the job
Instructions are very short and inadequate, took me 2-3 hours to work out how to use it, however it does what I want and the relay seems to be working ok with a 3kW immersion heater which takes 12.5 amps. On the label is says 10amps max at 230V, but on the relay it says 30 amps so confusing, but so far (only one day) the relay works ok and I hope it lasts. A very good price to do what it does but needs instructions (in English)
