I like that you can easily share calendars with clients, colleagues or friends on your team without having the same email address as them in order for it not be a hassle setting up meetings from different places around the world! The only thing is that sometimes there are delays of 5-10 minutes between when we hit send/receive until they actually show online so keep an eye out if this happens often! We've been able solve our scheduling problems by using timeflex because now everyone has access to everything at once instead of having multiple emails going back n forth before getting their schedule together.
