Easy to set up - works flawlessly! We have been using it for our WordPress website since day 1 of launch. It's so easy anyone can use this software without any expertise in Web Hosting or Website Development industry. There are no problems we've come across yet but I am sure there will be very soon if you're not familiar with hosting server settings like PHP version used by your web host. This has nothing to do with CDNs itself; rather its about understanding how servers work. With that said, I don't think they should charge anything other than free when compared against competitors which take days to setup their own solutions. Why would one want to go through all these hassle only to get charged? If someone really needs an awesome solution he'll surely find his way out eventually. Our site was just too slow before going live because Easy to use; very good customer support -- always willing help you out if there's any issue or question that arises! Great for CDNs - they have servers in multiple locations which makes it easy when looking into performance issues across different regions of your website / network where users are geographically spread from one another.
