I have a Roku Ultra LT and it is nice. When I used it for the first time, I do not have access on US channels. So I have set-up a Smart DNS on my TP Link 5400 router but I think i have to reset (reconfigure back to stock) my Roku since it is still regionally restricted. Am I right?
I have a couple of Roku devices at home. As long as you have Smart DNS configured with the region of the apps you plan to use pointed at the right country, Roku would work. I used to have my Hulu, SlingTV, and Pluto TV setup on Roku, but with the advent of IPTV's, Netflix, and Disney+, I stopped using my Roku's and are just sitting idle at home.
