Value for money is incredibly important to VPN users and straight away, we can see that AirVPN and BlackVPN provide access to three devices per license – one more than BolehVPN. All three offer their customers an easy-to-use mobile app, with compatibility available on Windows, Linux, Mac, Android and iOS. AirVPN are the only providers in this comparison to include a kill switch as standard, ensuring that any breakdowns in connection will retain your personal privacy and security. With so many VPN suppliers now available, it’s disappointing to see that BlackVPN do not offer any sort of free trial. However, they do include a 14-day money back guarantee, along with BolehVPN, although neither is comparable to AirVPN’s 30-day equivalent.
