-Fast (no lag)
-Incredible streaming quality
-Easy set up
-Longer range wifi
-Same compact size as previous generation
-Voice recognition on remote works well
-Comes with batteries for remote
The Bad:
-Have to resign into all apps but that’s not a surprise
The Bottom Line:
I just set up this new Roku Streaming Stick 4K and watched a movie on Netflix. I set up the streaming stick in less than 5 minutes. It took a little longer to re-log back into all my services like Amazon, Netflix, etc. but that was expected. As for performance, this streaming stick is faster than the previous generation Stick+. There is no lag whatsoever with this new one. The wifi is definitely longer range since I can move the stick to the garage and there is no lag when I move it out there compared to the older streaming stick. The picture is awesome and you can watch 4K without any issues. The remote works well and the voice recognition recognizes my voice well. If you’re wondering what the difference between the 4K streaming stick versus 4K streaming stick+, the only difference is the remote. Overall, I would recommend this new Roku streaming stick 4K for its streaming quality, speed and longer range wifi.

I went online and saw this one was being marketed as "long-range WiFi" and decided to go ahead and buy it. I can't express how much of a good decision that was. This streaming stick maintains a 4/5 connection at all times, loads instantly, and is in every way an upgrade from our 2018 Express.
I love how this remote has power, volume, and mute buttons for the TV too, that's very convenient. The voice control is great. Most devices can't understand me because I have a lisp, but this streaming stick doesn't seem to have any problems with my voice.
I'm always cautious spending upwards of $30 on anything because we're pretty poor, but in this case, this streaming stick was 100% worth the $50 it cost.
I was having poor reception with an older Roku stick as the TV was far from the modem. This new device is fantastic; great picture, speedy download speed and no loss of signal strength.
Highly recommended.
ADDENDUM: I have been using this 2021 ROKU for 4 days. This new 4K model is a game changer and I may switch my older ROKU streaming sticks to this new model; it is that good. It allows me to take advantage of the excellent resolution on my 4K televisions. My download speed is 144!!! I subscribe to a 500 speed from COX communication. The new ROKU device is far from the modem at the other end of a large home.
Full Disclosure: I am so impressed with ROKU products that I have purchased ROKU stock.
So, I decided that because this model was touting "long-range wireless" that maybe this would remedy the problem. It did not. The claims are that this model has 2x the wireless speed of previous Rokus. Maybe this is true, but the actual speed it does get is absolutely terrible.
I have attached two pictures to this review. One is of the wireless speed that the Roku is saying it has (purple screen), which is 2 mbps. Bear in mind, this is about 10ft from my wireless router. The second picture is of a speed test that I ran (on the WiFi) of my iPhone literally laying on top of the Roku at the TV and it is getting 122 mbps up and down.
So, you can see why I am having so many issues with streaming in general with this thing. This device is only capable of utilizing 1.6% of the speed that my wireless router is delivering. My advice to most people looking at this thing, avoid at all costs. There are many other streaming options that will reliably deliver the speeds you need for proper streaming.
Update: 10/23/21
So, after a week of pulling my hair out with this thing, I decided to format it to return it. Thankfully, I decided to give it one last shot before sending it back.
I’m glad I did, because after the format, it started miraculously working for about 3 days now. It gets 150+ mbps. I checked all of the settings to see what exactly had changed. Turns out it was my wireless router assigning a terrible channel to the Roku!! It put it on channel 1 initially. Same with my old Roku Premiere. Both were getting 2 mbps. For whatever reason, it assigned this Roku after formatting to channel 48 on my network and that fixed everything.
So, your mileage really may vary here. You may not have the router problem I had and it works flawlessly, or you may have the same or worse. I still kind of feel like this could be an issue involving Roku, like the Roku maybe should tell the router “Hey, this channel sucks, please give me a different one!”
I have updated my review to 4 stars because it is the best streaming device out of all that I have tried. Roku is a great company with a great UI. I just can’t quite give it 5 stars because of the WiFi issues because I don’t know if the blame is fully on my router, since I don’t have any other devices having issues.

No he tenido ningún problema de conexión, no cuando comparto pantalla desde el ipad.
El control es sencillo de usar y ligero y el comando de voz sirve a la perfección.
Ya incluye el Disney+ y yo descargué el HBO+ Y Crunchyroll desde la app y sirve muy bien.
Estoy muy satisfecha con la compra lo recomiendo bastante.

Do Aparelho, a qualidade é boa e o controle excelente, não tenho do que reclamar.

Roku's website also mentioned a/m channels.
However, Disney+ , Amazon Prime Video, HBOmax, discovery+ channels are completed unavailable.
Cannot even find in the device's channel list. Netflix is available though.
Does not support Bluetooth audio pairing. The sound is as good as what your TV provides as the only audio is going through the HDMI to your TV. Hence, when watching movie, you won't get the 5.1 or 7.1 effects.
Will not recommend to buy.
