Works as well as can be expected

Ive used it for years and its the only choice in PRC except ExpressVPN.

But guys you really need to add long/hard press on the icon in the regular menu to have option to turn on and off without having to open the app. Many apps have this like WeChat, I can long press then some options come up like directly to payment qr code. So let me turn it on and off via that long press, because one really needs to turn it on and off all day long depending on which apps we need to use. Thx.
