My sweet hubby is in the last stages of lung cancer and his voice is gone. I bought a new smoke detector and he uses it for a "beeper" if I am in another part of the house or at night when I am sleeping. All he has to do is push the check button.
Great Idea!!!! I had thyroid surgery several months ago & know all about not being able to get someone's attention who is in another room. Talking about a bad feeling. Sure wish I'd thought of this idea. Sorry about your husband's cancer. May God Bless You Both
