Ratings and reviews

I use it in China. Works pretty well. Holds and auto reconnects well on mobile. Occasionally there are periods with difficulty connecting, but that happens with all commercial VPNs.

I've used many VPN services, for over 10 years, and I must say that VPN.AC has always been my main go-to service. It's the most secure, fastest and most reliable out of at least a dozen that I've used, be it small or big services. Apps aren't as fancy design wise compared to some others, but the functionality is pretty much outstanding. I can only hope that they will include support for the Wireguard protocol in the apps, a much faster protocol than OpenVPN, which they already support.

Incredible amount of options and customization. Works in China. App Tunneling. Clear data visualization of speed of various servers. Ethical way of paying, choosing between subscription and one time payment, I did one time one month payment easily with PayPal. Affordable, cheaper than a starbucks meal for one month. No free option but that means good speed for paying customers. Not sure why the poor ratings. Better than Expressvpn right now.
