Before you buy you should be sure that you will really use a VPN.

Cons

There arent many cons to using a VPN, but the most obvious one is the extra cost.

Any decent VPN will cost some money.

Pros

ISPs have a history of monitoring and logging your internet usage data.

A VPN creates an encrypted connection between your gear and the VPN server.

The encryption that a VPN uses also provides protection against hackers on unencrypted public Wi-Fi hotspots.

A VPN encrypts all of your communications, keeping your data secure and private.

A number of sites, especially streaming websites, apply location restrictions on accessing certain content.

This can be useful to bypass these location-based content filters.

For example, Netflix only has a licence to show some content in certain countries.

Some services like Disney+ arent available in some regions at all that too can be circumvented with a VPN.

Only some VPN providers spend the time and effort to stay ahead of the VPN blacklists.

The ones who dont likely cant.
