good product

This is very good product but 2 item stopped working after 2 month, rest 3 still working since last 6 month

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.

Reasonable price

Excellent quality . Easy for. Installation.

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.
