Slashdot is no offering PureVPN for 5 devices, lifetime access, for USD 69.
If you don't know what VPN means or if you don't need it: don't bother. If you use VPN tunnelling on holidays etc., this is a great deal. Pure VPN has many servers and good reviews.
I've installed it on my MacBook Pro and on myPhone.
I notice that the tunnel built with Pure VPN is way faster and more stable than those built with my previous app, TunnelBear.
