The integration is very easy and I like that it's so customizable. It can be difficult at times when you're not familiar with Zapier or other integrations but the support team has been great in helping me figure out what I'm doing wrong. They are always quick to respond and help resolve any issues we may have. If you want something simple and flexible then this is perfect! There isn't anything specific that I dislike about this service. This integrates well with our calendar applications (Google etc.) and allows us to schedule meetings and appointments without having to manually enter them into Google calendars.
