Easy to setup, easy remote, easy interface. Even the app is designed right. Just make sure you use the power cable provided because inadequate tv usb power will cause performance issues.
I'm technophobic to the nth degree, but my Roku was easy to install and set up. When there has been a problem, it's usually been the result of my internet service provider or my own -- not proactively changing batteries on remote. Very important, especially for voice control, I've learned. Roku support, when needed (only once for me), was extremely helpful to resolve the problem (syncing tv and remote). The viewing options are virtually endless, I never lack for quality content that meets my viewing preferences. I highly recommend Roku.
Love it. My Television was not working well.once I connected my Roku Express 4+. I was able to turn TV off and on. Also up and down. This was a plus for me. I am very happy I purchased it. The picture is beautiful. Tks.
