It's very flexible, it has all the features we need for our daily operations and also gives us options to customize as per our needs. It allows multiple users access at once which helps in managing several tasks simultaneously.It doesn't allow copying files or folders between two different accounts. Also it does not offer any customizations to be done using APIs. I have used this product since last 5 years and haven't faced any serious problems like slowdowns etc.So far everything seems good about it but there are some minor issues which i would suggest they should try solving soon because otherwise people will start complaining to other providers who do provide better services than GSX gizmo. As compared with others,it provides many more benefits such as customization of dashboards/widgets, ability to make use of API integration with third party tools to automate repetitive workflows without writing code,flexible pricing plans and so forth.
