Rated 4 out of 5 by from Easy to use and install Easy to install on a 3 wire switch. Would recommend using electrician on a 5 wire switch. Once installed very easy to program. I leave ours on auto all the time. When you close the front panel one touch to overide the light. This wil not affect the timer working at all. Product could have a bit of a better casing has it looks abit cheap looking. Overall the product does the job i bought it for

Rated 2 out of 5 by from Doesn’t work with LED bulbs In many ways, this is a great product. Fairly priced, it allows you to replace a conventional light switch with a programmable timer to switch lights on and off. Admittedly as Smart Home technology becomes more affordable and practical, this probably seems a bit “analogue” but I found it great for switching on external house lights in the evening and overnight. Except it doesn’t work with LEDs - the nominal current that this switch allows to pass through the circuit (presumably to keep it charged) means the bulbs glow (or flash) even when the switch is off. Back to the drawing board.

Rated 4 out of 5 by from Great little timer. Bought and fitted a few now for customers, in a variety of applications but mainly the ease programming use with outside lighting projects. The longest one has been in for 12 months now with no issues. Nice that it's supplied with a spare fuse.
