I find It's fast, out of a base speed from ISP (VM) of 550 I get 520 24/7 from OVPN, that's 20 more than ExpressVPN has ever managed (I have a license for Express) - In fact, it's the fastest VPN I've used & tried most over the years. Its security is first-rate - I live in UK & get similar speeds from the EU & similar from the USA - I contacted support recently & they working on split tunneling that hopefully doesn't cause DNS leaks - Once again ExpressVPN leaks to your ISP if you tunnel a mail client such as Thunderbird which makes their Split Tunnel all but useless - If you want your system to run like you have no VPN try OVPN (and I got a T-Shirt)
I have tried numerous VPN services so far. OVPN works the most stable: No disconnections, no hangs, and quite fast speed. Wireguard is encryption is also available. OVPN is the only service that has convinced me so far. Well done, keep it up!
Not the cheapest, not the biggest server network, but reliable - very good and intuitive client software and administration in general. Wireguard support is a must for me... I've tried many others like ipvanish, protonvpn, nordvpn, etc .... but my ISP keeps blocking their servers (in Germany, not China!) - OVPN is the only VPN service working always.
