100% outstanding product
100% outstanding product.The only thing to be kept in mind is that you should place it as mentioned by the manufacturer.... or place this device on the eastern side of your building (might have to pull wires , if the light to be used is at western or some far place... Placing at eastern side will turn off the light at around 6am and turn it on by around 6.30-7pm depending on the lighting at your area.Its working perfectly for me for past 2 years. Highly recommended.You can know the quality of the product by just looking at the quality of the copper wire used.

Works perfectly fine, easy to assemble with little knowledge of electrical appliance. I connected this to my two gate lamp and now no longer need to switch gate lamp on and off every day. Even if i am away from home and traveling. The device looks nice even if it is hung outside on single screw.Two suggestions:1. Keep the wire little longer, considering the fact that you can not keep sensor just beside the lights other wise sensor will never work and so for a very short distance i had to connect small 20 cm wire to extend it.2. Both the sensor are tuned for different lux and so every evening first light starts and after few min the second one. This difference could be avoided. though it doesn't create much problem.Its working as expected since last week.Upade after more than a year-longOne is still working and other one stopped due to rain water. I shifted the connection under she'd to protect. In short, it's not water proof

Connecting wires are not Copper
The connecting wires are not copperSince these are used mostly outdoor there is galvanic corrosion when connecting with copper wires.Please use copper connecting wires.Joining copper and aluminum creates severe electrical and mechanical risks: galvanic corrosion, thermal expansion mismatch, and oxidation. Together, these problems increase electrical resistance,

LDR for electrical light control
Thus specific device from the manufacturer, I have installed on my house entrance light for automatic switch on after dusk. It is on service for over 4 years without any fault/failure which forced me to buy another for other areas.It is not expensive and a good value for money.
