    In Krasnoyarsk territory for 20 days. Packed in a factory box and a package, but everything came whole. I checked on the car exhaust. Sensor is triggered, readings scale up to 999 sensors Squeak without ceasing and even when removed from the exhaust and stands in the fresh air is not it stops pounding. You can reset only pulling out the battery. I do not know if it’s normal that it does not drop to zero, but that is what it is. I think it works. The sound of the siren is very loud. Shipping fast. Seller recommend.
