Used to be good, now it's horrible
It adds channels that you don't want, and several channels (Netflix for one) crashes all the time. Roku's support is useless

REMOTE
Roku is a great devise, but the remote
needs to be improve. The muting button
should be placed in another area; because it interferes when you hold the
remote in order to use it. It is too low for a right hand user.

Roku Ultra
I bought this to replace a Roku stick that I thought was going bad. Turns out it wasn’t stick but I still haven’t figured out issue so still trying to track that down . I previously bought an ultra since my Samsung smart TV kept buffering even though it was up to date. Liked the no batteries to replace which was a major factor but I prefer Roku over Fire stick so no bra...

Easy for everyone, no age limit
I love that the remote keypad is lighted and also voice enabled. So easy to add or subtract features like closed captions or listening levels. Go Roku!

Roku Easy to Use & Large Apps
My new TV is not a Roku TV, but I wanted to still use my Roku Streaming devices. I had to buy a new Ultra Roku & love the updates to the remote. The remote is charged using a “C” charger & the remote now lights up. The remote is simple to use. Less is More
Not too many buttons.

Great
With my new Roku Ultra, my TV turns on in SECONDS !! I don't have to wait and wait while things load and load,.....(: When I got it for Christmas 2025, I charged it for probably 5 min and I have never had to charge it since, even by today Jan 31, 2026. Great product ! I've always bought ROKUs and I always recommend them.

It's great!
It was a gift. I had the model below the Ultra & it was fine but the Ultra has functions that make navigating easier. I like the lights also. And your tech staff are terrific!

The best Roku yet
We had purchased a smart tv, that was supposed to be able to stream all of our channels. We were getting constant interruptions and signal issues with the TV and our internet. We placed a Roku stick on the smart TV, and all the issues were resolved. We went out the next day, purchased a Roku Ultra, and haven’t had a single issue. We recommend the Roku Ultra to everyone ...

Roku Ultra
I replaced a basic Roku that I had to un plug every other day so that the main screen would work and also on peacock streaming it was jittery after every commercial I had to go in an out of th app for it to work. New ultra Roku has been so much quicker and screen Quality is great. Just needed an upgrade

I don't speak French
It came out of the box in French.🙃🥺🤔
Thanks to the language translator and navigating through to the final set up then getting to the language change section
That was a real pain.
Now that it's in English everything works great
Do you check the language before it goes out?

Roku Ultra Upgrade
Had an old Ultra that struggled with memory problems. New upgrade works like a charm and the chargeable remote is excellent!

Movie fan
Very good streaming player. I only thing I don't like about it is that must be only 60 hz refresh rate, because there is a lot of motion blur. I watch the same content on the TV'S Internet system, and have almost no motion blur. The TV has 144hz refresh rate.
