Why a VPN?
Traffic encryption - prevents access to personal information, not encrypted network traffic is vulnerable to sniffing, especially when using Wi-Fi. Euro or USA IP - hides your real IP from the outside world, allows to use websites with geo-restricted access. An encrypted tunnel to the Internet - bypasses all possible network filters and website blacklists of the ISP.
It's a simple service which does not cause a headache. Max possible strong encryption. No bandwidth or amount of traffic limits. Best value for money.
