I was able to get it up and running in a few hours.
The good - if you are familiar with the Amazon interface and have Prime, it is a decent unit. It works well, software/apps run as good as any of the Android boxes I have had.
The bad - The little spat with Google is an annoyance as there is not much support for google software and apps. Sideloaded Kodi, IPTV app and more; which really just shouldn't be required. The interface is a little too Amazon and is not super configurable. If you want to add extra storage, you need to buy an OTG addon device, PITA.
Overall, a decent deal if you get it on sale. At full price, there are many Android boxes that are better.
