If you’re looking for a streaming device to plug into your television, you may well be eyeing up one of Amazon’s Fire TV range: the Fire TV Stick, Fire TV Stick 4K, or Fire TV Cube.

Why would you want a streaming device? Most televisions sold nowadays are what’s called ‘smart TVs’, meaning they’ll have Wi-Fi connectivity and be able to access a huge number of apps and services for watching TV and films on demand. That means you can watch Netflix, Amazon Prime Video, Hulu and YouTube all on your television, the same way you’d open an app on your smartphone.
