A single/occasional Low Impact is likely of no concern unless your vehicle is in a situation where something is more likely to happen to it. For example, in a busy parking lot. Multiple Low Impacts in succession, or Med/High Impacts in general, are certainly worth investigating. The Patented technology found within Bmmpr is finely tuned to monitor any and all disturbances- including small gusts of wind, earthquakes, or even small animals that may trigger the system. This is why we classify impacts, so you can be aware of what's going on with your vehicle at all times.
