Absolutely brilliant and easy to use!

This product has saved me an amazing amount of money and headache! I needed to connect my desktop computer (which I rarely use, but still need access to) and my laptops with one keyboard, one mouse, one USB connector for my speakers and microphone, and my WD Drive. Now, that was a headache and I was wondering how to find a KVM that would work when I stumbled across this product. Installing this is easy peasy. Computer 1 is my desktop; Computer two is actually my laptop dock, which has my personal computer and my work computer attached to it. I ran those USB cords first, then connected the keyboard, mouse, USB connector for sound, and my WD drive. Everything connected easily except my sound connector. I needed to update my drivers for that, but otherwise, everything was instant. I highly recommend this product!

Slick little device!

I needed a KVM Switch for my desk so that I could switch between the work laptop and my personal rig. Well, the V or video part of my needs turned out to be too expensive and too limited in capabilities, so I looked into the K&M or keyboard and mouse parts of my requirements. What I found was this device and few others like it. This is the USB 2.0 version and it works great. I plug the included cables into the respective systems (work laptop and personal rig) and then attach the devices I want to share between the two boxes into the other side of the side of the device. The top button is nice and handy and the LED lets me know which device is getting the signals. Nearly everything I've plugged into it has worked for sharing with one exception. Be warned, not everything may work with this device. I have a USB headset that has controls on the connection block for volume, speaker output and mic muting. This headset, a VTIN branded device, would not work with this KM switch. This has not a deal breaker as I don't need that headset on my personal rig at all, it's solely for my work laptop, as I work remote 100% and needed a decent headset for WebEx meetings and such. The work around was to plug the VTIN into the laptop directly and I'm OK with that. I haven't tried a web cam, but I don't do video meetings/Skype so I don't care. The headset or a WebCam may require more bandwidth. If you need to share these kinds of devices between two systems, you might look at the USB 3.0 version of this. It's like $10 to $11 more, but the increased bandwidth may be necessary to get the full range of device sharing experience. I still give it 5 stars, as it works great for the keyboard and mouse sharing which is why I bought it.

Works great for me...

Recently I developed tendonitis in my elbow because I was not ergonomic with my keyboard for my PC. I have a work laptop on top of my desk with its own keyboard and mouse. The PC is under my desk with a keyboard and mouse on a keyboard tray. + Setup this switch box in 5-min!! I love it comes with the needed cables to go OUT from the switch box and into a USB port; one on the work laptop and one on the PC. + I moved my better keyboard to the top of my desk and same with mouse. Plugged into this switch box and I was all set. The push of the button and there is a very short (2-3 seconds) delay between laptop or PC and I'm good to go on the other system. + I've been using this daily for a week and swap back 5-6 times a day (or more) and there have been no issues. If I have a USB drive plugged into one of the open ports on the box, the Windows system will auto-detect and allow me to use it on whichever system I'm live on. > I have yet to plug my printer into the switch box, but it too should work without issue, since my wifi connection to my printer is sometimes iffy. OVERALL: Easy-peasy solution. Around $20 solution. And now I'm ergonomic, regardless which of my two systems I'm working on. Love it!!

Works with Raspberry Pi

I use this with my Retro Pi/Raspberry Pi setups. My monitor has multiple HDMI ports, so I don't need the extra VGA connections offered by a traditional KVM switch, but having the ability to use 4 usb devices between my windows PC and my PI means that I don't have to keep an extra keyboard and mouse or disconnect/reconnect game controllers. There is a delay when switching, on the order of milliseconds,,,not long enough to be a problem, but just barely noticeable. If there's any input lag, I haven't noticed it.

Works like a charm

This little gadget has been an great addition to my work set up. I work with a windows desktop and my personal macbook, and it was a hassle having to move to type and having an extra mouse around the desk while using both computers on multiple displays. I use a software to share the mouse and keyboard at home, but since at work I'm on two different networks this comes very handy. I have my mechanical keyboard connected as well as a wireless mouse, and I get the 4th port open to use whatever I want in it, normally a thumb drive to transfer anything I need in between computers. The device is very well built and the button on it seems to be very solid. This fixed my problem, and so far, I am very happy with the product. The only con I have, is that it does not come with micro usb cable to power it up, but who does not have one of those available these days, not really a big deal.

No input lag for mouse/keyboard. No software required

I use the switch for my remote mouse and keyboard. Here are two things I learnt which might help other KBM users: 1. Responsiveness is unaffected. I was worried the switch might dull the responsiveness of my mouse or create input lag when typing on my keyboard. Both are things I hate and I'm extremely sensitive to. Thankfully there was nothing to worry about. My keyboard and mouse are just as responsive as plugging the receiver directly into my PC. If there is any difference, I certainly can't tell. 2. No software is required. The switch is plugged into two computers: my PC and my work laptop. The latter cannot have any software installed on it without admin permissions, so I was happy to see the switch works fine without any software. It really was as simple as "plug and play". I don't think Windows even attempted to find software for this device - none was needed,

Even I could install this!

Amazing! I didn't even have to ask my husband to make it work. (for context, I still don't know how to work the VCR or find tv shows). It was totally obvious and worked immediately. Nothing to do other than plug everything in and go! UGreen, where have you been all my life! No more unplugging and plugging and weakening my USB ports! Postscript: tested this at home (above review) and printer, scanner, labelmaker worked wonderfully on my dining room table experiment. Then I brought it to my office and couldn't get it to work. After much frustration and rejiggering of cables, I found a combination that worked - in part. It likes shorter cables. It also needed the extra power supply. I don't think it likes power hogs like printers unless you've got a short cable. Because I need a long cable to get between the two desks, I ultimately ended up buying a new printer so we don't have to try and share. So, this is now hooked up to the Dymo label printer and the Fujitsu Scansnap which both work great for the two shared workspaces. I'm still happy with it so will keep the rating.

Sweet!!

I have a Windows 10 based Laptop and Desktop PC. This Switch lets me use the same wireless mouse and wireless keyboard (one dongle) with both systems. Push the button, and the devices connect immediately to the other PC. Sweet !!

Stylish, Compact and Effective

I was looking for an alternative to swapping wireless keyboard dongles between my Windows Desktop and my Macbook Pro which is setup in a desktop configuration for the most part. The additional ports provide future expansion potential. The four port USB switch is well designed, well built. It has the same form factor as a normal USB hub and comes in an attractive gloss black finish. The included hub to host (male, male USB A) cables are high quality and plenty long (6') to easily run to both computers. What I like but others may not is that the Computer 1 and 2 position readout is just legible - the blue LEDs are run at low power - unlike the usual trend of products with obnoxiously bright LED indicators. Support for the switch is seamless and driverless in both my MacOS X 10.11 and Windows 7 machines. There is a OS specific setup time of 5 - 20 seconds when switching host computers. The switch has the option to be powered through an optional 5V input via a micro USB input ( cable not included ). For my low power application, the 5V input was not needed.

Two computers at one desk, solved. Extra wires, to manage, ugh

This really helped get my desk space issue solved. I have a work laptop and gaming PC sharing a desk and prefer to use my mouse and keyboard instead of the laptop's while working from home. I also need to be able to disconnect my laptop from my desk to go to the office frequently. Previously i was movingthe wires as needed, but the extra movement is bad for the life of wires. My keyboard wire eventually failed, so this helps with that. The result wasn't very pretty for wire management since the wires are on both sides of the device. Also in order to access the button I had to route the wires to the top of the desk, then route wires to my laptop. Doubled the amount of wires visible on my desk, but it's a small trade for convenience. The extra wires look worse when I remove my laptop. I might Velcro mount the button on the side of a desk hutch in order to clean up the appearance in the future. The button works fine and the response is fast. I don't have any noticeable lag from my mouse or keyboard while using it for games. The indicator light is a really helpful feature.
