Performance (speed & reliability)
Visit blackVPN

Speed is also an important point when choosing a VPN, the speed depends on many factors such as the server network of the service, the closer the server is located, the faster the speed will be, the encryption you use, the speed of your internet provider, all these factors affect the speed of your connection. We tested the speed with Speedtest and frankly I was disappointed with the results. First, I measured my speed without a VPN connection and it was 50.27 Mbps, then I connected to the recommended server and the speed was only 4.35 Mbps, which significantly reduces your speed when using a VPN, but in fact, the VPN server was overloaded and the second time the speed was 15.10 Mbps, nevertheless this is still low, and to reduce the load on servers you should expand the server network. Connecting to the U.S. server, my speed was 2.19 Mbps, which is extremely low because of server congestion. In general, the picture is not satisfactory, the service should think about expanding the network to avoid congestion, or optimize their own servers to achieve better results.

Features & Usability
Visit blackVPN

Unfortunately, the service is not multi-functional and does not have such additional options as split tunneling, ad blocker, etc. Let's consider what the service offers us, to begin with, the function killswitch, a useful feature, its action is to break your Internet connection when there was a failure in the work of the WiFi network, because at that moment, when the connection with the WiFi is broken, your confidential information immediately becomes vulnerable and it can be used by hackers, especially this becomes dangerous when you connect to a public network Wifi. Unfortunately, only the Windows client has this feature and sometimes there are problems with this option.

The advantage of the service is also the use of a NAT firewall which, when connected, blocks traffic that is not requested.

Bare Metal servers are dedicated servers, which can be used only by blackVPN users, the advantage of these servers is that they are not virtual, without an operating system and are designed to improve the security and speed of the connection.

During the testing we haven't found any leaks of DNS data, the service masked our IP and the testing revealed no leaks of confidential information.

BlackVPN app needs a lot of work, Andriod app can't connect to VPN server in any way, it's badly optimized, there are a lot of small problems that need to be fixed, and there is no killswitch function.

Windows app is better, but also has its own problems, without the OpenVPN client, you will be limited in accessing many servers, this is also a drawback of the service, I hope in the future this situation will be corrected.
