Very good product

Value for money. Bulky product.
It is over all a good product. Finishing is not very good. However cable connecters are of very good quality. Product is quite bulky. I had a LED light in my ceiling before fitting perfectly. But to install it i had to do some retrofiting just to accommodate its bulky body. Still hangs out a little. Other than that working wise works great as mentioned in description. Also can be installed to a heavier load of about 800W. And just so that there is no confusion among new buyers, its NOT a light its simply just a switch that is triggered by motion.

Works perfectly.
It does its job quite perfectly. Even when someone just opens the main gate of my house, immediately the light switches on and they get the feeling that we already know that someone has arrived, which is not really the case. So it's a nice thing to have. Makes your light auto on and off based on motion. Also, the range can also be set according to your needs. So far so nice.
