The ease of use, very helpful customer service when needed - fast response time to questions or concerns! I like how it integrates with my Google Docs so easily allows me access at any location via phone/tablet etc.. It's not as easy (or intuitive) in creating charts than other softwares but still doable if you know what your doing!! As mentioned above- great support team who are always willing help out where ever possible. Great product overall though could be more user friendly once used maybe? We have been able to save tons off our paper records by using this system instead which has made things easier both personally AND professionally since we no longer need all those files stored away somewhere else.
