I'm currently using TorGuard VPN Streaming Bundle - I get 2 static IPs servers (Choose between US, UK, Japan etc) - works flawlessly with Netflix, Amazon Prime and HBO Max.

I'm getting around 100Mbps connected to VPN server, my internet speed is 300Mbps. Decent enough for 4K streaming. I'm currently paying around $30.99 for 6 months. There's a lot of promo codes offering around 50% discount so you actually pay lesser than what was advertised.
