I had no success, at all.
Premiumiz.me as a "multihoster" does not work for me. I do not know about their other features like VPN service but if you are looking for a premium filehost downloader DO NOT SIGN UP. Nothing ever works. Filespace, Fileal, Turbobit, Xubster (...) everything is flat out marked as "down" (they only show this after you sign up) or as "unstable". And that basically means down, too. I had zero success in downloading anything. There might be one or two hosts (that no one ever uses) that are working fine. But if you are looking for support of hosts that are used on forums and blogs then stay away. Strongest warning.
