The biggest benefit of Life Alert is the fact that it acts as a lifeline to help in the event of a medical emergency. Simply press the help button, and you will be connected to a representative in a call center who can help you get medical assistance. Some services also include automatic fall detection. If you fall while wearing the device, the service will automatically contact you to determine whether you need help. If you do not respond, the service can dispatch medical personnel to your home to help you.
