Incidentally, there is a current VPN deal for 3 years worth of Windscribe Pro (ie unlimited access to their bandwidth, server locations and for any number of your devices) for US$13.50 (about £10), so it is under £3.50 a year.
Windscribe is not the fastest and greatest vpn provider around, but it is not too shabby either. A review consistent with my experience (I have tried their free sub before) is at

My PIA sub is running out in a couple more months, so I have just bought this 3 year deal - it is cheap enough as a spare.
OpenVPN with 256 bit AES encryption seems to be the only protocol they offer, which you might want to bear in mind (e.g. if you have to manual install on a device they do not support). That might also partially explain why their headline speed is not as fast as some, however it is an indication of their focus on security rather than speed, unlike some low cost vpn providers who give you pptp as standard, or even as the only offering. Personally, speed beyond 20mbps is of no importance to me - I have no need to download multiple huge files quickly, and 20mbps is plenty for streams I might need concurrently.
The founder made some comments last year about his outfit at
https://airvpn.org/topic/18488-what-do-you-think-about-windscribe/ - all in all it sounds ok to me, certainly for the price.
If you are interested, you can evaluate the deal by googling "stacksocial Windscribe VPN: 3-Yr Pro Subscription". Entering WINDSCRIBESD40 at the "Promo code?" label on the right hand side of the checkout page will give you 40% discount on the $22.49, so it ends up as $13.50. Don't know how long the promo code might last. The $22.49 price is supposed to expire in 3 or 4 days.
Cheers!
