I have a Roku box (the Roku 3 before voice search) on my TV downstairs, and just added a Roku stick for my TV upstairs. I cancelled my cable subscription a couple of years ago to save money, and I love my Roku. I use mostly Amazon Prime and SlingTV, but sometimes click over to one of the other apps. It is easy to use, and a real bargain compared to what my cable bill was. I will say that it is very important to have a decent internet connection- one that is fully capable of streaming media. If your internet is turtle-slow, you will need to upgrade to avoid frustration.
Constantly in and out connetion which I know isn't my wifi. The remote stopped working after a week. Searching for some things can be a little difficult. Set up is super easy just setting up each account I have cable for with each channel can be time consuming, it'd be nice if I could do all at once. I'd do anything to have screen mirroring capabilities on the iPhone. Setting up screen mirroring with a laptop that should have been compatible was impossible and controlling things from laptop to TV was a pain. overall some pretty good content and unique but searching can be difficult and having all of the default icons is difficult because i don't want 90% of them on my home screen.
