Этот VPN Premium? Удоляю..

Nordvpn is the best vpn proxy extension ever. I like it.

Funktioniert zuverlässig, Geschwdigkeit ebenfalls ausreichend. Einzelne Anwendungen/Websites werden ungewollt blockiert. Alle konnten mit Split tunneling gangbar gemacht werden.
Insgesamt sehr zu empfehlen.

This extension on Mac (maybe Windows also) is leaking your home DNS. Test it for yourself. Nord VPN recommends you use https://www.dnsleaktest.com/ this website will tell you all is fine. But if you use https://ipleak.net/ or https://www.expressvpn.com/dns-leak-test it will reveal your home DNS and who your broadband provider is. Don't take my word, check this for yourself. It's a massive security flaw.

no issues

Only been using it for a week now but, so far, it has been flawless. I'm used to having to manually connect to VPNs but having this extension do it automatically means I don't have to think about it. I'm also really impressed with speed. I'm not noticing any slowdown or lag with any of my traffic.....really liking it so far.

works a charm.
