In general, the impression is good! I would recommend this service. I bet 5 out of 5, might be 5 with minus as there were some issues with installation and configuration, though nothing serious.
For now, I am using secretvpn, have not met any issues with them yet, quite stably, large selection of IP-addresses, pitifully limited the free plan.
A VPN service which is definitely worth buying. There was never advertising or spam, support is always in touch, affordable rates. Special thanks for the connection quality and speed.
