I've been using Nord VPN on my desktop, laptop, phone and tablet for 2 or 3 years now. Occasional wake from sleep issues on the full system desktop and laptop have been an ongoing annoyance. Just started using the extension on the desktop and laptop. I like it better as the desktop version really slows down boot times.
My only beef is that it won't stay logged in on my Linux browser extension.
I'm keeping the full version for my phone and tablet as it works flawlessly with the android OS.
The browser extension on the desk/laptop limits the coverage to the browser, which is all I really need it for. No wake from sleep issues so far.
Well done
