Nord user for the past 2 years, I have never been disappointed. The app was recommend by few friends of mine who were using regularly because of traveling abroad, although I don't travel much, I still find it useful at home. I really liked the fact to connect many devices at once but lately I decided to install it on my router so as soon as everyone connects to our router, they are secured instantly. If I don't tell people, they don't notice it, especially knowing that there's no changes in speeds.
So far so good, I would definitely recommend, even if you're not someone comfortable with software, it's still easy to use.
