Product needs a technical upgrade!!
Though the product is functional but it needs to be technically upgraded. It works on a prefixed lighting level available/not available to switch off/on. In the areas where there is presence of some dull/distant light this product tends to malfunction. It should have an adjuster so that desired light levels to switch on/off can be controlled manually. Durability can be commented only once the device stops working/burns but anything beyond an year on uninterrupted service would be acceptable. The same product is available for much lesser price on some other sites. Installation was well explained and easy. Rest fine.

Works well
Installed 2x of these outside the house and its working perfectly fine. It saves time, as I don't have to constantly switch on and off every day. It is bright enough for night visibility, detects motion and is a good value for money.
