Uni-ComPlug-in Security Timer, Home Protection, Energy Saving Sensor, Easy to Use Random Pattern to Switch Lights On & Off

Just used this recently. Select winter or summer setting, plug device in then plug in the lamp. Switch on. After dark/dusk light comes on for about 4 hours (winter setting) then goes off and switches back on at random, through the night. Stops working when there is enough light for it to seem like the day's dawned.So if you pick a lamp that's too bright or shines on the sensor the device will not work correctly.Otherwise very easy to set up if you just want a light that comes on with no set pattern (The 'Wet Bandits', in the Xmas film Home Alone, deduced which houses were unoccupied, by recording the times the lights came on!). So, unless you want to rely on a child to defend your home, get one of these!

Easy to work! Tested it out over the last 2 days works fine! No noise … Overall 100%

I bought 3 in all but one does not work! I wrote to the company and have still not heard back ! You have to hope it works !

Very good no programing just plug in does it’s own thing great

No hours on spending to set it up just turn on appliance in question and follow easy instructions took me less than five minutes to install it.

This works OK but remember it will carry on working all through the night even though, when people go to bed normally the lights are switched off until the next day/evening so it can add to your electricity bill. Also if the day is overcast and your room may be a little darker some times it can come on during the day.

Perfect for what I needed it for

Seemed like a good idea, but as I live in an older house, it is in practice hard to plug these into sockets which receive sufficient direct daylight to operate effectively, even using extension leads. I'll continue experimenting.
