We just purchased this dual phone and answer machine to replace a Philips model that died a few days ago. On the whole I'm impressed, nice clear display, easy to set up, good quality feel, nice tactile buttons. It has some nice features including one to help locate your phone if it gets lost under a pile of papers etc.
I haven't used the answer machine yet but telephone calls are crisp and clear, unlike (in my experience so far) the other review suggests.
One criticism I have is the ringtone(s). They are all pretty awful 'polyphonic' tones, while this doesn't really interfere with the core function of the phone, it would have been nice to have a few 'normal' tones. Aside from that pretty happy.
