可能不是其中一个广为人知的VPN服务，可是凭借有 80 的伺服器遍布全球，每张许可证可供 1 部设备使用，让你会考虑想要使用他们的服务。 VPN4All 的价格排名 3.0，是从 $4.08/月 开始。
Obsolete software which will lead to demise of the service -- most of the software is compromised -- when you go to OpenVPN forum VPN4All is 2 or 3 versions behind -- I have one tech tell me to download OpenVPN community software and download just the TAP to correct a connection error -- I thought why am I doing this -- should the service provided update the software -- I change to ExpressVPN -- no issues same speed -- periodically updates to keep the software secure.
The Positives first: - Fast first response from Support. That's about all. The Negatives: - Their help turned out to be useless and no, I am not letting a stranger access my computer via TeamViewer. After that, no more help from Support, just silence. That makes tolerating the rest even less of an option: - Extremely ugly interface - Lack of server options (default is Russia, of all places) - No KillSwitch (at $84/yr you should expect that) - Slow, building the connection takes forever - No attention to detail (go to their Feedback page: the latest Windows version there is Windows 7) - The 'KnowledgeBase' is a joke: mainly one-liners that sound like ad copy (predictably, users are not impressed, just click 'vote' at the bottom and see how many users found any of the offered answers helpful) - Overpriced In short: there are much better VPNs out there. I use the market leader on the other PC and it works like a charm.
