This motion detector works well and is actually smaller than I expected. The only issue I had was the USB power port. The USB port is located right in the middle on the left side of the device. When mounted on the supplied wall bracket, the bracket is so close to the wall that it prevents the sensor from rotating to the left. Of course, the motion detector works and can be easily attached to the wall bracket if you use it on battery power. But I need my sensor in a high traffic area, so the USB power delivery was the reason I chose this particular device.
