The subscription is not expensive and there is no bandwidth or traffic limit. That already makes it a good VPN product.The Windows beta client almost never connects although the Chrome extension on the same device works without a problem. The PAC-like rule is handy, what it is now might be enough for browser but to be a global VPN, there is so much left to be done. The software really lags when you import a huge list which commonly works smoothly with a personally built socks server.I know China is not one of the regular places when judging a VPN. AdGuard VPN had been functioning properly a while ago but is getting less and less stable. It is common to see no available locations now. On Windows, I have a fallback v2ray server (based on completely free VPS, domain name, nat64 and CDN, so it not not going to be very reliable) which also helps it to connect to AdGuard servers. However on iOS, VPNs mostly cannot live together so the trick cannot be done and I haven’t figured out a walk-around.
Thank you for your feedback, yes, we are working on improvements every day.In particular, there were problems in China a couple of days ago, but we are trying to fix the situation very quickly.Denis,Product Owner at AdGuard VPN.
