I got my Fire Stick 4K yesterday and played around with it last night. I have been using Roku only for a long time so this was a different experience for me. Setup was very easy! That said...the interface is a bit overwhelming compared to Roku! I don't mean that it is bad...there is just so much going on when comparing it to the Roku interface (which may just be because I am used to Roku). Roku's design is very simple yet very effective. Getting past that, the picture on the TV streaming thru the Fire Stick is awesome! There were a few apps I couldn't find that I occasionally use on Roku but nothing major. Overall I am impressed in my first impression of the Fire Stick and will get used to it vs my Roku devices. For $25 I am very happy with it!
