I tried ExpressVPN, Windscribe and hide.me all get denied by my university's firewall even with TCP port 443. But VPN.ac with china settings XOR enabled manages to get through. Very nice piece of software.

Interface is nice and kill switch works well. No logs presumably In the Asia Pacific region there are not enough servers. It can take a while to connect to a server and drops outs are frequent during busy times. The kill switch works, but the software gets confused sometimes and I need to reset my adaptor before I can reconnect. My local area speed without VPN is around 30Mbs, and 10ms pings (measured by ookla). Using VPN.ac I can typically expect about 20% -50% of the bandwidth(6-10Mbs is common ) and pings of 200-500ms . It is a bit faster if I connect to the local country server(upto 20Mbs), but I use a VPN because you cant trust the Australia gov! I normally connect to the EU servers as they are slightly faster than the AP ones. But the distance means I take a hit to pings and speed. It has definitely got slower over the last year. Other than the speed I quite like it. I have used NordVPN and PureVPN. By comparison the VPN.AC interface is much better. Speed wise it was similar to Nord. I still have an active account for PureVPn, which is the fastest, but I do not trust the software reliability (or the company). The biggest reliability issue with VPN.ac is it sometimes doesn't connect and I am impatient and forgot to check it was connected properly before using.

I have been using the service since two years. But for the last 4-5 months, the service was blocked on du operator in UAE, for VOIP it only works with one ISP now - Etisalat. I am no longer able to make VOIP calls (Whatsapp) which worked fine with du + VPNC before. the VOIP however works with Etisalat as ISP on the same phone. I guess they got flagged.
