    • love my roku
This product is well constructed, easy to use, and does exactly what it’s supposed to do. It’s clear that attention was given to both quality and functionality. Very satisfied with the purchase!

    • Fabulous product that gave new life to my ‘older’ but excellent Sony 1080p TV
After buying a couple of Roku TVs, and realizing how great they are, I finally decided to cut her cable and convert my two ‘older’ TVs. My first was a Sony that we’ve hade for a long time and I used this product because I have an Ethernet connection inside the cabinet under the TV. I prefer to have TVs connected using Ethernet so as to reduce the traffic on my WiFi. This product has both WiFi and Ethernet so a big plus there. Installing the Roku was easy, my HDMI cables were already in place. I really enjoyed replacing the huge, heavy and very warm cable box (good riddance ). With the Ethernet connection, the install is rather boring. I plugged it in and was left to complete the installation using the remote. The next part of the install was to set up the TVs 1080p screen and the remote. My TV is 1080p and the device discovered that and set it automatically. I was very pleased that Roku remote can power and set the sound natively without having to use the TV’s remote. After years of using multiple remotes and the kludgy CableTV remote, it all works as one! I’m particularly pleased that since AppleTV and AirPlay are supported, that knocks another remote to the curb. Going through the device setup is easy and Roku will ask questions about your preferences in order to tailor some of the apps/channels it puts on your Home Screen. It takes a few minutes and is very straightforward. One thing that I really love about this Roku is the remote. It has the voice control (works great to turn on and off subtitles or switch channels, for example) and a headphone jack for private listening. Honestly, the most satisfying part of the remote is it’s feel. It is a bit weightier than the Roku remotes I got with my Roku TVs and just feels great in my hand. I wish Roku made the TV manufacturers using the Roku OS also use the nicer remote. I just love the remote, even if first timers always ask how to change the volume! Finally, using this as a reason to get deep into the TV cabinet and behind the TV, I was amazed how heavy (and dusty) that TV is. The newer TVs are so light and thin! This Sony is a helluva workhorse tho, and the picture is flawless albeit 1080p. I think it will be a while before there is enough 4K or 8k programming out there to make a difference. This Roku device is a fabulous product that gave new life to my ‘older’ TV. Thanks for reading! ... show more

Its everything I could have expected, a highly competent streaming player with all the options. We're definitely power users at my house. This has an extra powerful Wi-Fi if you are going to stay wireless, and also supports wired ethernet without an extra dongle (FireTV), if you've wired your house with CAT 6 ethernet like me :) . I already have a 4K TV with LG OS, a FireTV stick, and even a Tivo Romio Pro that streams. When my LG TV, FireTV, & Tivo use Wi-Fi they spend noticeably more time opening apps and opening shows than when connected via wired. With this Roku, the Wi-Fi seems nearly no different. I still connected it via Ethernet in the end, but was surprised how equivalent Wi-Fi seemed compared to my past experiences. Its hardware is fast and reliable, such that I've never perceived a delay induced by the hardware. Easy to configure out of the box too. The menus and channels are really easy to navigate, and easy on my eyes. And it supports seemingly all relevant audio and video formats like Dolby Vision & Dolby Atmos, which it audio-detects level of HDR support in your TV. The remote is probably is probably its most multi-faceted and yet simple and intuitive solution. It has volume buttons or mute on the right side by your thumb. it has a headphone jack on the left for silent watching if you don't want to disturb others. It is an RF remote meaning you can tuck the Roku away in a cabinet or behind a TV and it will still work without line-of-sight. But the Roku does have an IR sensor if you have another IR remote too. And most of the buttons are what you'd expect on a modern streamer, but feels simple, easy, and intuitive to use. The skip-back button (like my Tivo button) is something I use a lot, such as if I missed something or didn't hear them quite right. Surprisingly by default it displays closed captioning (subtitle) on the replay so you can see what they said if you were backing it up. But you can turn that off CC on rewind if you rewind often and don't want the distraction of text. And the voice-command button and subsequent command processing is surprisingly good. You can even say things like "skip forward 2 minutes" or whatever. And you can even save your last voice command in one of the two numbered buttons by holding one after, and then repeats that command if you touch it again. I actually use that a lot to skip for ward 30 seconds :) . However, some possible minor negatives are: (1) There is no 30-second instant skip-forward button on the remote. But you can use a voice command to skip any amount of time you want, including 30-seconds, and can store that in one of the configurable buttons. It just isn't exactly instant skip while it processes the command, but close enough. (2) Pausing and resuming leave the screen darkened and showing the progress bar and controls and takes a few seconds to resume normal brightness of the show or movie. That irks me compared to my LG TV that the back button can hide the bar so I can instantly be back into my show in its full picture. (3) Streaming apps may vary by platform, so don't expect them to be identical. For example, I REALLY like the Netflix app on my LG TV for #2 and for fast forwarding that can click right or left through easy picture snapshots rather than a traditional fast forward or rewind that appears in the Roku version of the same app. (4) The volume buttons on the right-side of the remote are easy to accidentally press if you aren't careful, but doesn't really get in the way. (5) If it doesn't detect Dolby Vision, double check that the device it is directly connected to supports it on that HDMI input. Definitely not the fault of this device, but it puzzled me for a while why it didn't detect Dolby Vision at first when my TV supports it (the TV did, but the HDMI input on my Blu-ray player didn't). Roku supports the widest channel library that I am aware of, and is the reason I bought this, for HBO Max. I use this when I want the best sound support to go through my sound system and it delivers a noticeable sound improvement in my home compared to my TV connected back to my A/V receiver. I actually have this plugged into the HDMI In port on my Oppo 4K Blu-ray player. ... show more

    • Best Streaming Box... But Not Perfect
Generally great. I was tired of my PS5 not having incredibly basic streaming apps on it, and didn't want to pay the Apple tax just to stream things in 4K, so I took a chance on this during a sale. It's paid off well. 4K quality is great (I'm wired in, can't attest for wifi), it's responsive, and I love the hefty but light remote and it's easy to use buttons. The only downside is that you cannot manually power it down. I don't know why, it goes through a speedy boot-up process when you plug it back in, seems like they easily could have added that in. I just don't like vampire devices sapping juice, even if in "low power mode" (which I don't totally buy, when you're running a CG fish tank screensaver nonstop), so I've taken to just unplugging it at night. Hopefully, eventually, they add this feature in. Doubtful, as I'm sure it's tied to some predatory usage/stats scam they have going on like every player in the streaming game, but at least this was fairly cheap and works how I want it to. ... show more
