Well, I’m using the free version - since I only get to use it during this period when I’m unable to access anything which doesn’t happen frequently I just didn’t think it was worth paying for any vpn. I have used only two different VPNs and both of them were free and they both showed slow network connection.
That's not surprising then. As mentioned above, free VPNs are slow most of the time. I think buying a paid VPN is worth it, whether you need it for casinos or not. I bought Mullvad for months now and it's quite cheap at 4.5 Euro if you paid with Bitcoin. It doesn't slow down my internet connection at all and there are dozens of servers that you can choose if you think the speed is slow. Not to mention you can ask for a refund if you're not satisfied with it. I think most good VPNs do that nowadays so there's no need to buy the long-term plan to try the service.
