So far so good. It was a 5 minute plug and play. We've got about an hour of talk time on it and the sound quality is great. The only difference from the land line is that it is a little bit louder. Just as clear, but I had to click the earpiece volume down one. People on the other end say it doesn't sound any different from the land line. The best part... we're now paying 75% less for telephone service.
