The Perfect Core for a Clean Daisy‑Chained Setup
This switch has become the central hub of my AV chain, and it performs flawlessly. I’ve paired it with an HDMI audio extractor and two short 0.5m HDMI cables to build a compact, tidy daisy‑chained system with zero clutter. The switch handles both of my input devices instantly, with no handshake issues, no flicker, and no audio dropouts. It’s reliable, compact, and works seamlessly with the rest of the chain. If you’re building a modular setup and want something stable at the heart of it, this switch is spot on.

SABRENT hdml 4k switch
So far, the switch is working with no problems. Quality of build is ok, lightweight. The device is functional and working as intended.it is extremely easy to use and setup. Just make sure all hdml cables are firmly connected. There is a manual switch, which toggles between the different connected devices. And a power indicator light, which is not detracting. The default is the left sided hdml port. Speed of switching is good. Picture quality is fine. Brightness is good. Though this also depends on the quality of cables used and correct signal frequency set. No flickering had been notice. Durability should be good for this switch.

Extremely reliable, study, but requires more ports, and pretty overpriced.
I needed the ability to ONLY switch a wireless keyboard and mouse between two computers As such I didnt need a fully fledged KVM, just a USB switcher. I have dealt with various USB switchers, and most non mainstream branded devices are pretty terrible. Either they are unreliable (often either disconnecting, or even not properly switchin) or downright harmfull to equipment due to poor seperation of signals and power. Some even use non standard connections (such as a USB A socket for INPUT as well as OUTPUT which not only is non compliant to USB specs (which are strict about that stuff), but also potentially harmfull to your equipment if you connect stuff wrong. I had earlier bought a Sabrent USB-C KVM for my wife, and was impressed with its quality and reliability so when looking for a USB switcher I chose this product despite being quite pricy for what it is, and also only havign one USB port (though in my case I only needed one). The product is definately well made and correctly uses full size USB B sockets for the Input. I switch frequently between the two computers, and it works well, never lost connection and has a little LED showing which input is connected. My only issue is a) its price, I cannot see how it costs that much to make but I guess it doesnt have much in the way of branded quality competition. My wifes USB C KVM which is also by sabrent, and has far more features, including a hub, video, and USB PD was not that much more in price. b) for that price it could have easily had 2 output ports, again see above.

Perfect and works as intended
They work exactly as intended. The bottom of the control pad is flat enough to accommodate magnetic tape Another reviewer noted that the PC changes automatically. I have not found this to be the case. That must have been a defect.

Hdmi 2 Way Switch
Simple switch to give extra hdmi for your TV,my TV only had 2 hdmi sockets, one used through the Hifi, the 2nd for a Google cast, this allowed a extra connection,you just switch between the two channels.

Keep it simple
Update 2: It gains one star because when it is plugged directly into both computers, it does perform flawlessly. Don't connect it to USB hubs/docking stations; use those for less critical devices. Update: It loses another 2 stars. It currently only works when both PCs are on and in a state where they both recognise USB devices. I upgraded one PC (new motherboard) and now this happens. To use it with only one PC on I have to disconnect the unused cable. Very annoying. Original review: If you use this within reason it functions perfectly. One wired low power keyboard shared with two PCs using USB 2.0 cables and USB 2.0 sockets on the PCs. It loses one star for two reasons: It is back to front on your desk - the two cables going to the PCs exit toward you and the device cable (KB/mouse etc) goes in at the back, unless you turn it 180 degrees with upside down Sabrent branding. A ridiculous oversight to be honest. The blue LEDs are barely visible from an angle because they are resessed and shine through a small narrow black hole. Bright blue LEDs are annoying though so this might be a pro for some people. You can improve the visibility by applying little paper sticker dots over the holes or you could rub some white candle wax/silicone/glue/translucent stuff into the holes.

Compact design
Used to switch a mouse between computers, works perfectly. Well built, also remembers which port is selected.

I am glad I found this little gem. I use 2x PC's and a Laptop that gets connected to my main external monitors. I use to have a keyboard/mouse combo for each of the 3. Now, with this device, I have only one set I use for all 3. I was always having trouble with the networked printer, now the printer swaps directly (via USB) to whichever device I am active on. It also makes swapping files from one to another simpler. I recommend this for anyone just looking for a keyboard solution for multiple devices. But it is capable of much more.

It's intuitive to hook up and use, and it works for switching a USB hub with a connected mouse, keyboard, and Yubikey. I haven't tested the USB throughput, so I can't speak to that. Only downside is that the LED indicators are a little dim and hard to see in a brightly lit room unless you know what you are looking for. This could be a good thing if you are using it in a darker room (e.g., watching a movie). It's not a big deal and you'll quickly get used to it. I'm happy with my purchase.

I kept buying generic USB switches that are just rebrand of another manufacturer, and they all had a common problem. They all had ghosting key presses. They would either not register a key stroke or double up on a key stroke. They often randomly stop switching all devices attached(mouse, keyboard, webcam, headset), and would bug out. Sabrent is a well known brand, and so far this thing hasn't dropped a beat. The price is great, even less then some of the many others I've tried. While this is working well, I haven't had it as long as the other, so this review may change in the future. If it last a year without bugging out, I'll be happy. Pros: 1- Switching from 1 PC to another is quick, with no delay. It's only as fast as your OS will register the peripherals being connected. 2- Can have a USB micro connected to give additional power to the USB devices(I havent needed it, but glad it's an option). Cons, every product has at least 1: 1- The USB cables that connect to the 4 other PCs(if you want to connect to 4, the option is there, I needed 4) is attached to the HUB, so if you only need 2, you have to cable manage the other 2 lose cables. Not a huge deal, but worth mentioning. 2- The button to switch, while big and responsive, only cycles through 1-4. It would have been nice to be able to press, Left for 1, up for 2, right for 3, down for 4, or something. Again, not a huge deal, but it can be annoying hearing the other PC's make the USB connecting sounds when rotating through. That's it. I would recommend this one for sure even with the cons, since it hasn't been ghosting my key presses, and switching to the next PC instantly with no delay.
