If you are in the US, do you use a VPN to play on gambling sites like Roobet? If so, which VPN is the best to use in your opinion?

I use Express VPN since I trust them to do what they say they do. That said, I would not recommend that you use a VPN to try to bypass poker sites GEO location restrictions. The risk of having your funds confiscated is not worth the reward of getting to play at the site.
