I love how easy it is once set-up; my assistant can enter all of our schedules in seconds! The interface isn't as intuitive or user friendly at first glance - but that's why there are training videos available!! If anyone has questions about certain aspects they should contact support immediately because we had several concerns answered quickly by them (and even an hour later). We started using this service two years ago now so not much time yet since implementation though everything looks great from what i've seen thus far.
