I decided to try them out by downloading their android app (to be able to apply for the 3 day trial) After getting a "problem contacting the server" error, I sent them an email regarding appliance for their ios beta app through testflight. As they did not answer, I went for a monthly sub as I thought there would be no harm in this, regarding their 14 Day Full Money Back Guarantee. I downloaded the macOS client + configuration files and got it up and running though i found the setup somewhat complicated compared to other new friendly providers. The interface was for me somewhat clunky and buggy and therefore I tried contacting them again to apply for their Money Back Guarantee. Still no answer. In conclusion I cannot recommend blackVPN because of this: Emails and ticket system seems abandoned just like their android app hasn´t been updated in nearly two years?
