I love that it's open source software! It makes for an extremely secure VPN connection without many of those annoying proprietary applications out there in other companies' product lines (like CyberGhost). Also nice is how they are constantly adding new features to make their service better than others'. One thing though--it can be hard getting people who have never used this type of system before up to speed with its use. Keep at them until you get 'em trained good like me!! Great way to keep your network safe from hackers or anyone else looking to gain access through any means possible by using another person/device as cover via proxy connections. Best because we trust our security so much more while still maintaining full anonymity when needed. The software works like a charm -it is easy to use with no hassle. Very fast to connect and set up. I have a couple of windows 7 PCs with my home network attached to them. I use this for file sharing purposes as well. Sometimes it gets stuck when connecting but it doesn't take long to get back online again and everything works just fine. All computers are connected to another NAS device that I share files from. It's basically a file server in my house.
