Many years ago, over 15 I guess, I purchased one of these for my upstairs study. Just recently it kept loosing the set time and I was happy to buy a replacement, which is now working fine. There is a battery backup somewhere in the works - I couldn't find it and it's probably hard-wired in. I guess that bit finally failed. Fair enough after all those years.

Does exactly what it describes. Smart light technology may overtake this but, for me, it does a great job of switching on our porch lights every evening regardless of whether or not we are home. OK the switch box sits proud of the wall but it's a tidy and discreet looking unit. Really pleased and will probably order a couple more.

I had one similar 15 years old in the hall controlling the Porch light. It's brain became addled when it was 'off line' for 8 hours, so I bought this one. It is ace, easy fitting instructions, and easy setting up the periods of 'on/off'. Works like a dream.

Good price. Purchased 2 of these items and work very well. No problems fitting them although I had to buy some longer screws for 1 of them. Needed some electrical knowledge to wire up for 2 was switching though. Easy to set up & program.

Bought this to replace one I have had for many years to operate a porch light.A great security device to operate the light when on holiday.
