This was a gift for my husband, he spends a lot of time watching TV. He absolutely loves this! He uses it on an older LG TV and it works great! Roku has so many streaming options!
My TV had insufficient Ram to reliably handle all being asked of it. The Roku 4K device solved the problem immediately. I suspected that was the problem. The solution is a little klunky, but very much less expensive than replacing the TV. Hooray for Roku.
