The only flaw I don't like about it is the call log and caller ID. The handsets aren't linked so that when you review your call log on one handset it notes that on all the others. So one handset will show that you've missed several calls when you actually got them or reviewed the call log on another handset. Also, the caller ID isn't coordinated with the phone book. The call will show a generic listing as "wireless caller" when I've programmed my phone book with that number to come up under a specific name.Otherwise, the phone's great. Great reception, very clear, love the expandable handsets, the speakerphone is high quality, etc...etc...
