2 were purchased and one was placed in the car's fairly large (double) garage and the second one in a hallway. Easy installation, works properly as it should, the range is satisfactory (at least in my spaces). The purchase is worth the money.

Small vertical window, horizontally it is about 170 degrees at 2 meters, vertically much less. It does not adjust easily and sticks if you want a different angle.

Excellent performance in motion detection, very good and easy adjustment of standby time and sensitivity. Easy and simple installation.

It has all the settings, but I don't know if anyone wants to make it very or very little sensitive if it suits them.

Very good and fast detection. I don't know if it's better than those with Microwave, but this one is effective. I tested it up to 6 meters and it's fine

Easy installation and does its job as promised. Immediate response to motion, under any lighting conditions, up to about 4 meters - as far as I have tested it. These are my observations for the first 1 and a half months of its operation.

Perfect !!! Very good performance and it actually works as a presence sensor.
I bought three pieces and they were so good that I ordered two more for different areas in the house.
