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.

Average product
Average product functioning. Timing function doesnโt matter to work very well. Low to medium accuracy of motion sensitiveness.

BlackT microwave sensor alarm a good security choice
As there were several robberies in the compound decided to install BlackT motion sensor with a light and buzzer alarm. Over the past few weeks it has been working very well switching on when any one moves infront of it at night. Saved a lot as watch man not needed who any way goes to sleep anyway

Excellent product
Product is awesome. Just gave it four stars as when it starts it relays power to the load. Thereby making it unusable with siren systems even light bulb lights up for the durationnof time set.
