had picked up a new 4k 65" tv and initially purchased an new v2 ****** firetv box. noticed stuttering, audio sync issues and sluggishness at times. returned the fire tv box and got the roku 4 ... night and day difference UI is so much faster, 4k netflix playback is crisp and smooth, and roku media player is now as quick and behaved as anything else Ive used to play local media back. Highly recommended
ROKU 4 is buggy. It only wanted to connect to the 5g connection. The screen blips every once in a while on 4k. I needed to lower the resolution to 1080p to get it to work like the ROKU 3. While makes me wonder why I got the ROKU 4. I would wait until all the bugs are works out.
I have had my roku for a month or two and while it is great and has many features the platform or OS seem to have issues from time to time. Hard to wake up, runs hot, feed barely works, network time won't stay on automatic, resolution issues with 4k causes me to have to reset it to factory sometimes.
I bought this to replace an older model aND I love it. My picture quality as well as sound is outstandingly much better, crisp, colorful, and clear.
I bought the ROKO-4 a few days ago and set it up within minutes. Using the device is very intuitive and easy. I began streaming immediately. Device works well.
Tons of channels!!!!!!!! Easy to use!!!!!!!!!!!!!!
I cancelled my cable subscription and have no regrets thanks to my roku. And I still get to watch the Super Bowl live thanks to Rokus free cbs sports channel.
