PureVPN is a garbage, i bought once from them because they offered 30 days money back guarantee, so i didn't hesitate to try them out yet it wasn't as i though. They do offer alot of servers & locations, but what's bad with them is, they are cheap, trying to attract users with tons of overloaded discount-gimmicks, and with slow, super-cheap servers hosted at.
The problem here is, FinchVPN has clean users, thus, servers are at peace while PureVPN is big company, but being big comes with extended issues and problems. This is why i like FinchVPN to be as it is now because, the more they grow, the bigger issues will appear to pop-up.
Im sure FinchVPN is aware of it, thats why they don't do marketting tricks like others do, because they already get paid decently right now.
FinchVPN is way more advanced than others, it's Android app + Windows Client is alot more advanced than other VPNs.
No matter what you say, i tried CyberGhost VPN (Premium), ZenMate (Premium), PureVPN (Premium), HideMan VPN (For Android only, as a Premium user), PrivateInternetAccess (PIA, as Premium user), and i swear, among all those, FinchVPN is BEST!
It's simple, hassle-free, and fast, much faster than any other VPN out there i tried out.
