I signed up a few months ago. It seemed to get good reviews. I have no idea how to tell if it really does what they say though.
I'm not tech savvy.
Hopefully somebody who is will chime in and say I didn't waste my money.
They're all about the same IMO. You may get different speeds from the different ones. Offhand I know of Nord and Norton, but there's quite a few out there.
Basically, you're protecting your traffic from potential hackers. It doesn't really do much to protect against tracking, since you're still making the connection from point A (your computer) to point B (wherever) via your ISP. More than anything, it protects against hackers monitoring your traffic in an attempt to get ahold of your logins, credit cards & banking info, etc.
You get a LITTLE privacy because the VPN exit point is what shows up as your location. For example, for work I use a VPN, and when I'm logged in to it, websites detect my location as Reston, VA. When I'm NOT on it, my location is detected in Utah (which I guess is the home base for the satellite I'm tied to).
Norton is US company and subject to turning data over to government. It's best to find an off shore company, that is safe from the US government.
Pretty much the same for most jurisdictions. You should see the EU rules.
If your intent is private, untracked browsing, TOR (The Onion Router) is the way to go. But that comes with its own set of drawbacks - for one, many sites reject TOR traffic. There's ways around that, too, but it starts getting complicated.
When I'm on TOR, my location shows up all over the place. I've seen Britain, Russia, Slovakia, South Africa, China, etc.
Cnet has a good list of VPN services, including legal jurisdictions:
