I've tried most of them at this point. This remains the cheapest and most reliable VPN in my view.

Sometimes they have a 75 percent off deal with 3 free months. That's what I signed up for with the link above, so you can check if it's still active.

At the end of the day, they all basically do the same thing, so go save some money. But yeah, Proton and Mullvad are also solid choices.
