This is a very good, simple set of portable phones with a base answering machine. There are actually more features that I will probably never use, but they would be important for some people.
It's convenient to set up and retrieve messages. It would be nice if you'd include some setup documentation when it's replacing a base unit that died; i.e., was hit by lighting. I would strong recommend the article "how-to-register-an-orphaned-att-92370-handset-to-a-different-base-station".
