Since there hasn't been much discussion about the answering machine function, I will address that. It took a good deal of searching to find a decent cordless phone with individual mailboxes. Seems like the market for this kind of product is disappearing (not unlike "pure" PDAs) due to the plethora of cell phones and voice mail boxes.
This product has three mailboxes, each of which is connected to its own light on the base unit when there is a message in it. These lights (actually, more like individual parts of a circle) flash when there is a new message and there is a display of how many messages total there are on the base unit. You can leave yourself voice memos in any of the mail boxes.
The message quality itself is average - a little tinny but not bad. The default announcer's voice is female, robotic, and slightly annoying. You have the ability to record two outgoing messages and easily switch back and forth between them - nice for the holidays, for example.
The handsets are lightweight but slightly awkward ergonomically. You can name and choose from several different ring tones for each handset in order to distinguish them. As noted, there is a paging function that works best if the phones are all on the same floor. The product comes with three handsets and you can add another if you would like.
One feature we really like is the intercom function, which is easy to operate and makes communicating from different parts of the house much more fluid. There is also a function that allows you to monitor sound in any room there is a phone, which could be useful if you have small children... or for other purposes that are beyond the scope of this review.
I've only had the phones for about a month but in that time we haven't had any problems. Reception is good all over the house despite a wireless router, Bluetooth devices, microwave, etc. Pretty happy with the product so far.
