I like that it's super easy for my members who are in different time zones, especially with our work hours changing every day - we have people from all over US east coast as well! The support is also top notch :) It was pretty hard at first getting used too but now its working great so no complaints about this one :). You can use their integration services if you need help setting up your own integrations or customizations of features/schedules etc.. But just be patient because sometimes there could take some extra days than expected while someone works remotely (which i think should not happen) otherwise nothing really negative yet!! Just try using invite robot once before making any decision whether u would continue being an invitor yourself instead since everyone needs something helping them automate things which makes life easier ;) We've been able solve many problems by automating tasks previously done manually including.
