In case anyone is interested, I have used these other VPNs, some of which I half-recommend, though I always come back to Air:   Mullvad: "trustworthy" but hardly any servers (just five servers), and their client is rather basic. You have to enable various settings for proper protection which are left unticked by default. Not a patch on Air.   IVPN - too expensive and their client was not so great. Did not go back.   hide.me - apparently trustworthy, but their Windows client does not protect you
