Query: Ineffective, Fault-Prone Technology

I bought a Siemens Gigaset 4015 and several 4000 handsets a year ago, and have had nothing but trouble with them. They cut off phone calls in mid-conversation, and are so unreliable, I can no longer use them. I've called Siemens Technical Support multiple times, and am given useless troubleshooting tips. What's been my solution? I bought an inexpensive AT&T cordless phone from my local drugstore, and it works like a charm. The low $ AT&T phone beats the higher $$$ Siemens phones hands down. I don't buy all the excuses that try to make up for the Siemens cordless products' faults -- my AT&T cordless works like a champ in a home that has a wireless network, where I use my microwave, and where I do all the other everyday things a good phone should be able to handle.
