I started using BlackVPN on the recommendation of a friend, I do a lot of international travel and as such get hit by a lot of problems due to geo-location. The last case was me not being able to modify a scheduled PayPal payment as I wasn't visiting the site from a US IP address, BlackVPN now solves this problem for me. Not to mention some of the wireless networks in hotels and airports can be a little shady, BlackVPN again solves this problem. Granted I have had problems with not being able to connect to certain sites, connections dropping out etc... but after reporting these issues they have been fixed in a matter of hours. Overall I'm very impressed with the service they provide.
