Should I use this while traveling?
Yes, a VPN works well while traveling or using any untrusted WiFi like a coffee shop, hotel, or airport.
To get the fastest speeds, choose a server location near where you will be traveling.
Hotel WiFi has had horror stories of injected and changing webpages (adding advertisements, adding banners). Generally, we don't trust WiFi when we don't know the motivations of the person running it.
