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.

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..
