JerseyExcellent choiceReviewed in United States on Aug 30,2019I’ve only had it about a month, so I can’t speak to about reliability, but it seems to be decent quality. With electronics, my experience has been that if it hasn’t broken in the first month it’s probably going to be OK.mapleleafthey were just what we were looking forReviewed in United States on Aug 30,2019WE had been looking for a system that we could but in our out building areas so we could communicate without the yelling system being needed.This system works great. We have one in the house, one in the shop and one out in the tractor barn. These are very easy to use and are loud enough that they are easy to hear. Very clear. Wish we had made this purchase a long time ago.California SisterMy ultimate home phone for my business.Reviewed in United States on Aug 30,2019Fantastic phone.
