Great product
have been using these microwave sensors for about 6 months now and they are very useful and works superbly. They can be adjusted to your needs in terms of sensitivity, time delay, and range. I have 3 such sensors at home conveniently placed where not frequent movement happens.. and kids sometimes forget to switch off lights.. this is a major power saver..

Very nice
I love the operation of the product. It works only when it is dark if you set the LUX sensor appropriately. It turns on immediately when I open the door.However, the timer isn't accurate. Sometimes, it switches off at the set time, and a few other times, it takes a few seconds longer. The device looks a little cheap. The company definitely need an English-speaking employee to correct their English in their manual/instruction.Overall, it's a fantastic product. I will order more of them for all my lights and recommend it to all prospective buyers.

Good one!
This is a good product.The issue I face with this is there is some flaws in motion detection , Many times even if there is no motion it blows the light. And The point is the issue is in its main functionality , It should be fixed and should be more accurate.

Works as expected
Nice and small sensor. Can be installed without any tools. I have sticked it to the roof light using hot glue. Keeps sensing activity and light does not turn off untill the room is empty. The sensitivity setting is another convenience feature. You can limit the radius of movement sensing.Very happy with the buy.
