What do you want to know exactly? It is a good VPN for a decent price.
First of all, it is based in Panama which has no data retention laws and out of 14 eyes jurisdiction, it also does not collect any logs. Secondly, it is secure (you can read more about the protocols and encryption
here). Thirdly, it supports streaming of various services like Netflix, iPlayer etc. thanks to SmartPlay or so it seems. Finally, it supports peer-to-peer, torrents (even though it doesn't support port forwarding), has various features like CyberSec, DoubleVPN for extra paranoid etc.
If you are talking about the software side of things, I'm using Nord on my Macbook, Galaxy S9+, and Win10 machine: it is easy to use and it just works. They constantly update the apps too. If you are using Linux it could be more problematic because they do not have a native Linux app; it is relatively easy to set up though.
So yeah, depends on what you need from a VPN. As a well-rounded package, I think it does the job well.
Some reviews if you are interested in that sort of thing.
