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.
