The sound is pretty good, certainly better than the last two house phones I've owned, and the speakerphone is certainly loud and clear and this, along with reliability were the two key elements I was looking for.
You can also use both phones when on a call to someone, which almost feels like a kind of accidental conference calling ability, which is a bonus for when the kids want to talk to their grandparents!
There are only a few ringtones, but then I don't think I've ever heard a ring tone I actually liked.
Setting up is pretty much straightforward, instructions barely required (I am a man).
It's a bit annoying having to create two phone books, but that's life I guess.
Overall, for the money, reliable, clear and so far no major issues.
