I like that they are very reliable, always respond to emails in timely manner (even when you don't expect it). They have been able to help us with our projects since we first started working together almost 5 years ago now! The customer service has improved over time as well - which was something of an issue at one point but not anymore. We've had some issues along the way where things were going wrong or taking longer than expected; however these problems can be solved by contacting them directly so there's no need for any complaints from me about this aspect :) It would also benefit their business if more people used other cloud storage providers because then customers might use those instead rather than relying solely upon Dropbox/Google Drive etc.
