We have a multistory house and kids all over it. The intercom is a nice way to get them to meals or tell them to get ready for bed without running all over. It has worked well. Sometimes cb users can be heard. We live near a highway. Probably happens once a week.
I got this for my grandmother to be able to use to contact me since we're on different floors I put one in her bedroom and one in her living room it's loud clear enough for her to hear me through even without her hearing aids
