Nord was pretty good and fast, but...
Since last year their browser extension has been secretly throttled. This was confirmed with their devs after multiple emails to support. They never told us about this throttle and the website continues to advertise that they do not set any limits. Most likely their support even dont know about it and will tell you otherwise, which will just show how they can make such serious changes even without careful considerations within their team.
I gave some time to see if they will fix it but after a few months it didnt sound like they cared at all. If you are reading this you probably are interested in using the extension and not the desktop app, so my advice is dont get Nord now unless you are good with being slowed.

Update:
It is the case. Anyone can try to download a file and see for themselves it can never go above a certain speed. I see some previous reviews that mention this too. Just like I said pretty much no one other than devs knows about this.
Ticket 15039623

As of June 2024, this extension severely throttles internet connection speeds.

Using NordVPN without the extension is no problem at all, but the browser extension quite literally slows your experience to a halt. It's unusable. If you haven't purchased a Nord subscription yet, and you are hoping to make use of the browser extension, look elsewhere. All of the 5-star reviews for this extensions are likely out of date, and or posted by people provided with financial incentive to do so.



TL;DR
Steer clear.

I do not recommend:
1. Long technical support answers (12-24 hours), formal answers, asking for things that have already been answered earlier.
2. This is not a free application, but any payment automatically makes a subscription to you, it is not written anywhere except Help Center, it also says that a return is possible only for the first payment, the rest is not returned if they are not forced by law.
3. VPN program automatically install 2 more programs with self, one of them consumes traffic, when VPN does not work, removal does not help, the VPN program will restore them ...

very slow with inconsistent speeds. the full desktop version works fine though.

нужен vpn чтобы заходить на недоступные сайты, но у них самих сайт заблокирован🤷‍♂️

Look for another job If you are not able to make a usable extension. It would be better for everybody. I had to downgrade to Version3.3.0, and that still works perfectly (right now)

Used to be pretty good. Now the speed is capped on extension. If you go to speedtest.net it will show fast speed. However other test websites or actual file download is capped at exactly 10mb/s. You can see that the speed will briefly exceed 10mb/s then push back down. If you download 2 files, each files will only download at 5mb/s. This has been going for months. So much with their "no cap".
