Our Siemens 4215 system is the best we have ever had and have expanded it with 3 extra handsets. I unfortunately left the master set outside overnight and it rained on it. After drying it out a couple of days it actually worked again but then failed later. Not expecting to be able to replace it we were thrilled to find a used one on amazon. It works perfectly and saved us from replacing the entire system. Thanks Amazon!
