Review: A must required device - Have been using for more than a year. No complaints. Easy installation. Very useful as it saves lots of electricity as we tend to switch off the lights. Very Good quality as I have installed outdoors in rain and sun.
Review: Good and extremely sensitive - Product quality is good, easy to install and configure, but it’s extremely sensitive to even the light from the bulb, it just keeps automatically switching on and off, I had to wrap two sides with cardboard so that it stays on after dark, a dial to adjust the sensitivity could have been given to adjust the levels of sensitivity.

### ⭐⭐⭐⭐⭐ A must required device
*by P***P on 12 September 2025*

Have been using for more than a year. No complaints. Easy installation. Very useful as it saves lots of electricity as we tend to switch off the lights. Very Good quality as I have installed outdoors in rain and sun.

### ⭐⭐⭐⭐ Good and extremely sensitive
*by P***P on 7 November 2023*

Product quality is good, easy to install and configure, but it’s extremely sensitive to even the light from the bulb, it just keeps automatically switching on and off, I had to wrap two sides with cardboard so that it stays on after dark, a dial to adjust the sensitivity could have been given to adjust the levels of sensitivity.

### ⭐⭐⭐⭐⭐ Excellent quality product, value for money.
*by P***R on 16 August 2021*

Have used this sensor in my parking lot so that it turns on the common lighting system when it gets dark and automatically turns off when it gets daylight. Much to my astonishment the packing was neat and clean and 5 such devices for less than 1000 is a real value for money. Did go through the circuit and the components used and I am much impressd. Not sure of its durability if I am going to use it for exterior light as the Sun is pretty hard on plastic objects in Chennai. But sure the product will last long if used in non sunny areas. Just the manual could have been more detailed for a non technical person... net net a very excellent product.
