My mother has the basic in-home only service. After testing several times the service works, however the operator cannot hear my mom clearly even if she’s screaming in the next room from where the unit is located. She has be in the same room with the unit for them to be able to hear her, and likewise the speaker isn’t loud enough for us to hear clearly outside of the room, even at maximum volume and with the door open. Additionally it has taken over a minute for an operator to answer when testing the system, but they will eventually answer. So while it functions as intended it would be vastly improved by making it easier to communicate with the unit, and also by a faster response time.
