It is very easy to use. You just have to create an account first then it is good to go. The speed is also good compare to other free VPNs. Using this for two years and I am satisfied.

Scam, asking the registration

好用

很久以前安装过，感觉效果不大好就没用，过了一阵打算清理扩展，删前重新试了一下，居然好用了，虽然速度不算快，下载大概20-80k每秒之间，但胜在注册挺方便，注册后就很干净清爽，连接干脆，不像其他扩展一样要不是连半天连不上，就是假装连上了实际什么网页都打不开，或是一堆注册手续。希望能一直继续保持吧。

Good free VPN, but sometimes loosing free servers
UPD: NOT free VPN, only premium access

Was top, but today stop working for free.

Just stopped working one day.
no free location available.

Disabled my account for non use about 3 months ago and then removed most countries from the Free list.

牛B且有免费
