RE: 15 minute response time Guarantee? Parhaps someone should talk to you and ask you if you know what you are talking about. Cardiocomm is not an emergency response provider. They are providing a service to stop the need for emergency response. So if the people walking down the streets with the risk of heart attack are brain dead, then I get your point. If they are not, I sure hope they are not, then I suggest you do proper DD and understand the product.
