I have only tried nordvpn, so my opinion is limited. For me, the speed look great, only a slight speed drop, that's hardly noticeable. What do others think?
I've got a 170mb up/down connection that pings at about 7ms and the ProtonVPNs free service gives me 40mb down, 33.5mb up and pings at 20ms. That's connecting from the UK to Netherlands.
Doesn't make any difference for browsing.
I'm happy with that so it's the only one i've tried. Other than access to more servers, is there any reason to pay!?... except I can't listen to BBC!
