Certified refurbished products are pre-owned devices that are thoroughly inspected, cleaned and tested to perform like new. Defective parts are replaced and software is updated to the latest version. A one-year warranty also protects your device if you are to run into any trouble. The Fire HD 8 does not come with a case, but we've rounded up some of the best ones here.

The Fire HD 8 is a minimalist, budget tablet that's best for streaming content. You get a 1.3GHz quad-core processor, 1.5GB RAM and an impressive HD video playback – though videos streamed from the web may be slightly grainier than content streamed from Amazon Prime.

In our review, we were particularly impressed with how sharp an episode of Mr.Robot looked when streamed from Prime. Overall, the Fire HD 8 is best suited for those with a Prime membership, as this unlocks much of the TV shows, films and apps offered by Amazon, but a Prime membership is not necessary to use the Fire HD 8.

You can sign up for a 1-month free trial of Amazon Prime here, which you can cancel anytime.

The £20 discount on the device comes before the 4th October release of the next generation model, the All-New Fire HD 8, which is hands-free and Alexa-enabled. Here's what we know about the All-New Fire HD 8 so far, including details on its new docking station and upgraded specs. You can pre-order the All-New Fire HD 8 for £79.99.
