Summary: We have been using this for a month in our house, and it has provided solid performance. It is much better than the Seimens Gigaset 2420 that we used before. With the 2420 we frequently heard static, and the range was poor. The connection would often drop when using the 2420 wireless handsets. This was true even when we shut down our wireless router, so interference from the router could not be blamed on the inferior performance of the 2420.
Summary: I got this set for 2 years now and it works just fine! The sound clarity is great! Because the main receiver is corded, it will also work during power outage! The battery life of the secondary units is more than adequate! The menu is fairly easy to use and the answering machine works great!
