For us its been great - their customer service has been fantastic and their technical support team is super helpful. They have been able to assist us in multiple scenarios with unique requirements. We had them set up an internal network (a number of computers) so we could easily share files and folders across those systems without having to use cloud services. It's really good! I was looking at other alternatives when they came along and decided to give it a try since i needed something secure, cheap & free.. They fit all 3 categories very nicely. Their software is easy to install and use, no complicated user interfaces or configuration required. Its very fast too.
