So far it’s worked great: The VPN connection is established within a few seconds and all applications are able to access services through the VPN tunnel immediately. 

Browsing speed over wifi doesn’t seem to be impacted at all, as I’d already mentioned in my first look.

My only gripe? An on/off switch for your default VPN connection that’s accessible from the top Settings menu (similar to the current “Airplane Mode” toggle) would be useful for users who frequently need to access the VPN client.
