4 Port USB 2.0 Sharing Manual Switch Box Hub 4 PCS Share Switcher 1 USB Device for Printer Scanner Camera Keyboard (4 Port)

I bought one of these some years back so I could use my printer with two computers. The unit is designed for use with up to 4 computers although I only have two. To my great surprise, the unit worked very well and has held up over time with much use. I just got a second (color) printer and as I still have two computers i decided to buy another switch unit so I could use the new printer with either system - just like the older printer. The switching is positive and the button actuation "feel" is top notch. If you have a need to share a printer with up to 4 computers, this is the printer switch to buy!

I was looking for the input and outputs working the opposite way but couldn't find it. Although this is advertised as one-way, it worked for my needs and i was able to use it for multiple printers connected to my computer. Awesome product, especially for the price. Easy and quick set up for connections.

6 months later, switching between ports 1 and 2 daily has become more and more unreliable. As others have noted, the electrical contacts seem to be degrading. Symptoms are that periodically, the devices lose their connectivity and reconnect. As time went on, this happened more often, and seemed to accelerate. Now sometimes the devices won't reconnect. For now, I'll switch to ports 3 and 4 and see if I can get another 6 months out of this. I suspect it's the contact points within the switches that are wearing down. Since those are the only moving parts. ---- good value at $9. physical switch, so it's like plugging and unplugging the device. not perfect, but works better than the emulated switches if being able to see the peripherals is important. Also no worry about the computers being connected to each other and causing problems. The physical switch prevents that from happening.

I took a chance because the price was low. I have multiple USB sources I want to connect to one DAC. I had to buy A to B adapters, but they are much cheaper than cables. I now have 4 devices connected to the DAC. It works. They sound fine. The only con is the manufacturer's logo on the top of the case. I'm deciding how to cover it up. I am curious how long the mechanical switches will last. If they're decent quality they may outlast me. I hope I don't have to update the review.

I bought this to replace a UGREEN 2-port switch because I needed another input jack. After spending far too long looking at the various switches that met my requirements, I stumbled upon this one. At $7 why not give it a try! I have a Nextiva SIP desk phone, a computer, and a smart phone connected to the inputs. The output is to a USB headset. This allows me listen to music on either the PC or the smart phone, and if a call comes into the desk phone, or a Teams call is started on the computer, I can easily and quickly switch to the appropriate device. I've had no reports of degraded microphone audio, and I have not noticed any impact on audio coming from the headphones. So far it's working very well. No complaints. The unknown at this point is how long it'll continue to function. Given that this thing uses mechanical switches, it has the potential to work properly for a long time.

This thing is great! So great I actually went back and bought another! Unlike most other ones of these, this is a nice, clicky-clacky mechanical switch powering this thing. It's not one of those all-electronic ones that switches away every time you plug something in. Plus, unlike most of them, the buttons are on the front meaning you can stack things on top of this and still have access to the buttons. And those buttons make all the difference too. You're on 1 and want to go to 4? Press 4. You don't have to 'cycle' through them like you do on other units, which, by the way, can confuse the machines they're connected to, seeing a usb device get plugged in then instantly ripped out again. This avoids all of that. Plus... it's just so fun to click! Even when it's not connected, I still use it like a fidget toy. :) The only 'knock' I can give against this is it isn't USB3, only 2, and it still uses the older USB cables you don't really see that much anymore... the ones with the 'chamfered squarish' plug like you see in the back of a printer, labeler or copier. Then again, chances are that's exactly what you're going to be plugging into a USB2 hub so that may very well be a benefit being able to use the same A-B cables for both the input and output.

Bought them twice. Worked maybe once or twice. Not worth it.

If you have one printer to share with more than one desktop and/or laptop, this is an easy, simple way to do it. I usually prefer wired to wireless connections in general. If you don't want to deal with setting up a wireless network and all the possible problems setting it up, then this is the way to go. It only takes the time to plug in the cables. Since it doesn't come with any cables, you will have to buy the type-A to type-B printer cables, unless you already have them. I gave it 4 stars because the housing felt a little flimsy, otherwise it works perfectly fine.
