I'm a caretaker for 3 family members. I put a ringer in each of their bedrooms and speakers in the rooms I'm in the most so I can hear. What is great is you can customize a ring tone for each ringer. I know which one of my family members needs me by the ring tone I have set for each one. Very cool! My disabled brother has a ringer in his bathroom, the ringer is water proof and has been holding up pretty well.
