Summary: Thought the sync may help with my business efficiency only to find out it does't work with outlook 2013 and Panasonic is not offering any solution, no work around, no plan for a fix. Very disappointed, last panasonic product I will buy. 2013 is almost over and the version of Office came out mid 2012.
Summary: Getting to the phone book on the handsets takes too many key presses, there is no way of telling if there is a message waiting from any of the handsets, the range isn't very good and since the phone doesn't fully implement the DECT protocol you can't use a DECT repeater with it.
Cons: Expensive, Difficult to use, Poor documentation
