When I purchased the Amazon Fire TV box I wasn't sure what to expect, I had previously used my LG TV's smart TV capabilities, but found them slow and somewhat limited, I bought the Amazon Fire TV box because I had read reviews about it's speed and I wasn't disappointed, it's so fast to load apps and move around the menus I would never go back to my smart TV's interface. I am an Amazon Prime customer so I instantly saw the benefit of having this product, it's the best way to watch their content I have seen.
The device works really well for Netflix and iPlayer as well, both much faster than my smart TV or Xbox ever were. I can't sing it's praises enough.
A final word on the remote, it's lovely, very well made an easy to use, I honestly thought the voice commands were going to be a gimmick, but it's just fantastic, it works so well, only criticism would be please allow other apps to utilise it, it's so good!
