The ease with using it! I can log into my patients' information without having them come back later or waiting until after they leave work each week (which sometimes takes hours). Their support team are quick to respond whenever there's an issue as well; no need to call multiple times before someone gets around to helping you out - just one email will do instead!! There might be some minor glitches here & there but nothing that would make me want not use C9 anymore if i were still working somewhere else. It truly makes life easier when we have such simple tools available through our phones these days like ours does now.
