The app works very well – Astrill VPN Client Review

The Astrill VPN app works great in China. It's a constant battle with the Great Firewall to get reliable and fast connections outside the country and Astrill has performed well for me. No VPN will work flawlessly 24/7 but the Astrill VPN app comes close. Realize many reviews here are for things other than the app as Astrill sells a router based VPN service that you program into your router (which works well for my Xbox and Amazon Prime Video). They also sell a personal wifi router with their VPN service built in (this one doesn't work so well in China). So read the reviews carefully before deciding.
