it does change your ip BUT it's on OVH's infra and I chose "Poland" but got France instead because the IP ranges are funky at OVH (I worked there so I know what I'm talking about)
It is basically a U VPN clone or they're the original? Idk, wouldn't recommend it tho.

I specifically need a free VPN right now to access a global website on it's Polish page but it has a geolocation "feature" that won't let you pick the country, so yeah.
