I like that it has options to send documents directly from my phone! It's easy, fast & efficient because of all its features which help me in sending files quickly without any hassle or confusion as well!! Nothing at this moment but i think there should be more security measures so user can use safely their data while using app services provided by them. So far everything works fine even though we are still newbie users here :) We have no issues yet regarding our business needs since they work perfectly together when used jointly along other tools suchas Google docs etc.
