My Wife has one of these so for the price I grabbed one for my self. This box works great and has a very good quality picture and lots of free stuff to watch.
It set up in a few minutes my WiFi was recognized and connected within seconds.
Fast delivery, good price and good quality what more could you ask for.
Thanks!

I had to replace my aging Roku 3 since the YouTube App was having sluggish performance. Part of the setup was a breeze since I already had a Roku account. I would have given a 5 stars if it wasn't for the hassle that I encounter at the beginning where the Roku Express 4k could not remember the Wi-Fi it connected on everytime I turn the power off then turn it back on later. I had to do a "Network reset" twice and a "Device restart" twice to make the device remember my Wi-Fi to connect automatically. Ever since then, everything work out smoothly, especially for the YouTube app. Other apps like Netflix or Disney+ work flawlessly. I would suggest the manufacturer to optimize the remembering the Wi-Fi connection, since my old Roku 3 never had that problem from the start. Other than that, very happy with purchase though, cause I really like the simplicity of the interface compared to other streaming devices.

I've had a Roku TV for a while after ditching the expensive cable prices. As long as you have good internet it works fine but you probably need a few additional apps to make the most of it. Picture quality is good but I suspect that depends more on the TV than Roku. Easy to install, a bit cumbersome changing channels but so far it is working as advertised. Your streaming can sometimes be delayed if you want instant access but overall worth the price if you aren't attached to the network real time programs. Everything is out there, just a bit later than real time.

We were having issues with the TV remote so purchasing this product solved them
One problem, this product does not have a power or volume buttons. Easy fix!!
I eventually called Roger's technical and they paired their remote with our TV.
Problem solved.

Our previous Roku stopped working after 4 years and it just made sense to get another Roku. This one is 4K so an upgrade from our previous one.
You still need two remotes but I donโ€™t care. You can also use the app on your phone to control programming and channels. I was worried that I might need my daughter to help me with setup but it was so simple. Very happy ๐Ÿ˜Š. I did forget to delete previous Roku account prior to setting up the new Roku account oops ๐Ÿ˜ฌ๐Ÿ˜… but this is a simple Roku support call. Itโ€™s working perfectly. ๐Ÿฅฐ highly recommend ๐Ÿ˜Š

If you dont have a smart TV but want the smart capabilities this will do it. This one is 4k quality so that is nice and you also get access to the Roku channels. The remote is fine but if you dont like it you can just use the app on your phone. It also has a nice aquarium screen saver.

5.0 out of 5 stars Quick & Easy setup
Reviewed in the United States on June 3, 2024

I initially went with Direct TV streaming with AT&T, and thought I was getting a bundle deal with WiFi. Apparently that was not the case, and there was no way I was going to pay $100/month on top of the $90 I was already paying for WiFi, so I canceled the direct TV. Why am I sharing this? Because the set up for the Direct TV streaming Gemini kit was horrible. It took a good 45 minutes to set up, and each time I was trying to go through, it would restart for some kind of update. Even entering the alpha numeric was painful for user name and password. In comparison, the setup with Roku was done in 10 minutes. Everything was convenient, it even gave you options for email suffix! Even the remote was convenient, which by the way, I was confused by reviews complaining about the remote not controlling the TV, when literally it asked me during set up if I wanted to configure the Roku remote for the TV. I am able to Turn on the TV, as well as control volume. For a one time payment of $39, and still having some access to live streaming, as well as other apps, I felt this was by far the better bargain.

1.0 out of 5 stars REMOTE CONTROL IS VERY POOR QUALITY.
Reviewed in the United States on March 28, 2024
Verified Purchase
IT WAS MY UNDERSTANDING THAT THE REMOTE CONTROL HAS NO BUTTON FOR SOUND OR THE ABILITY TO SOUND UP OR DOWN AND IT HAS A BUTTON TO TURN ON OR OFF. When I asked to return it or exchange it with a control that has these abilities, they said, either we charge restocking charges, shipping and handling, or no refund at all. Very bad way of doing business. I DO NOT RECOMMEND BUYING FROM THIS SUPPLIER. I AM A HANDICAP CAN NOT GO AND TURN ON OR OFF OR THE SOUND. IT IS WRONG REMOTE.
