Hide.me (formerly Hide.io) is a high quality VPN that guarantees no logging, even for free users.
Pro No logs are kept, it's completely anonymous
Because Hide.me is based in Malaysia, where there are no laws that would require a company to retain their data, the VPN service has chosen to avoid logging any personal data. Actually, no logs of any kind are kept. This saves them from liability and ensures your privacy.
Additionally, if the Malaysian government would change laws requiring retention of logs or customer data, Hide.me promises to change countries to be able to protect your privacy.
Pro No traffic or protocol restricitions except for US
You can use any and all protocols at your disposal, no traffic is restricted, except for US where P2P and BitTorrent traffic is restricted with a firewall. Additionally, users are encouraged to avoid US/UK locations for their filesharing activities.
Pro Free plan
The free plan allows for 1 connection that's limited to 3 servers (Canada, Netherlands & Singapore), 2GB of data, 3Mbit/s of bandwidth speed and it doesn't support OpenVPN. There's also the "plus" package that uncaps bandwidth speed, increases data limit to 75GB and adds OpenVPN support. Finally, there's the "premium" package, that uncaps data, allows for 5 simultaneous connections and port forwarding.
Hide.me software works on OS X, Windows, Linux, Android, Windows phone, and iOS. They also have a well-maintained blog which has a How To section which gives you a step by guide to set up Hide.me VPN, even on devices like PlayStation, Roku, X-box, various routers, etc.
