Huge upgrade over previous versions. Setup was a breeze with importing settings from previous fire stick. Remote synced with TV straight away. Menu is clean and tidy, much improved over previous version. Extremely quick and responsive. Picture and sound quality are great. Why we have had to wait for this in Australia for so long is mind boggling. Still need to play with voice controls more, but first thoughts are they are quite good at knowing what I am trying to get it to do/find.
