They’re saying for use in China lol (using HK servers). For a long time ExpressVPN was the defacto VPN for China. Today all off the shelf options will have some level of reliability issues. The ones that work best are usually a little sketchy so you need to feel comfortable trusting them with all of your internet data. Best option is to set up your own bespoke VPN server. This is cheaper in the long run, more reliable, more private, and more secure.
