Not quite what i expected. Being a Prime Member is was lead to believe, from various sources, that it would come pre-setup with my account details. It was not.
It's not the most intuitive device to work with. After watching several YouTube videos i worked through the process. Ironically getting YouTube on the device, that was in an acceptable format for me, proved a waste of time.
So i just ended up mirroring my ipad screen through FireTv onto the TV screen. Probably in the long run i'll just look at the ipad.
The FireTv screen is cluttered... and i'm yet to figure out how to un-clutter it.
In retrospect i probably would have been better going with the Roku.
