I have it Andy, it's pretty good, I think.
Buy your subscription on line, but buy a firestick with Kodi on it from eBay.
It'll cost another £15-20 but you'll have hundreds more channels on your tv. But you need to keep Kodi up to date, just by using it, it updates.
You'll have access to movies as they hit the cinema, and in HD.
The firestick plugs in to your HDMI socket on your tv and has its own power supply. That's it, done!
Search for new input on your tv and select firestick, it's that simple.
I download movies on to my phone or iPad so I can watch them if I'm commuting by train.
And to be fair it's all fairly current material, in comparison to other streaming services like Netflix. Plus obviously you also get free delivery on almost everything from Amazon themselves and it's nearly always next day delivery.
