I like that it has all of my contacts in one place, which saves me time when calling for an appointment or checking to see if someone called/texted while out running errands! It's not great at keeping track where you've been with your phone so sometimes i'm missing calls because they don't show up as missed until later (sometimes hours). Also can be confusing navigating through different pages depending upon what number its associated wtih - but once figured things work well enough though this isn’s really something negative about their system either!! We're able now keep our calendar organized by having appointments sync from multiple sources into 1 location instead of manually updating each app separately & then have people add themselves via email etc..
