If you're like me and took the plunge to 4K this is something you simply must purchase. This has everything you love about the Roku with the ability to output at 4K. It also has a nice feature that will show you all 4K content across all services Netflix, Amazon, Hulu and many more I've never heard of before. There is even more content than I thought there would be in 4K. It has all the same functionality as the Roku 3 and a few new functions my favorite is if you push a button on top it plays music on the remote so you never will lose your remote again. All in all this is my favorite streaming box I've tried the Amazon fire and the Apple TV this seems to be the best all the way around.
