Nvidia Shield TV is the best streaming device. They sell for 199.99$ It has google assistant,Plex add many other apps. Add Kodi and you are ready to go. It runs Nougat 7.0 and will upgrade to Oreo 8.0. Thorstream is 5.1. One of the problems with TV boxes is they don't upgrade the Android O/S. When apps upgrade they need a newer O/S, so in a year or so your box can't run the app. The problem with generic boxes is the company releases new boxes and the previous box is forgotten(no updates). You can get a better box than Thorstream from ebay for $36.00 w/ free shipping
