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

Excellent product. No complaints.

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.

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 bought this originally to switch one printer between two computers. It worked perfectly. I now use it to switch one keyboard between two computers. It works perfectly for this as well. Two minor issues: 1) the "buttons" require a firm push to toggle between computers, resulting in the switch moving on my desk -- I had to tack it down with double-stick tape, and 2) it would be helpful if the two buttons were lighted to see which computer is active.

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.

Quality is not the greatest they feel like they are ready to fall apart. They work ok not that great and at times it doesn’t even recognize my printer

Well, I honestly did not think anything good will come out from this device. I was looking for a USB 2.0 Type B splitter but could not get any.. However the switches I have seen so far (this one included) had the undesired in/out direction set. Was at least looking for USB 2.0 in with 2 TYPE B OUT. But this was the contrary... Yet as I was browsing to order something else I added this one with NO expectation at all... thinking it's just $8 and worst will trash it... But oh BOY! Was I wrong! This not only sat very well where I was needing it, blends in very well, and top of it the switches buttons do work well as intended between both connected computers, and though the direction of the in/out is not what I expected, yet it carries EASILY both ways from my Mackie ProFX 16 mixing board (in/out and out/in)..I can easily record sound through the box into my audio software, and playback sound into the mixer perfectly through the same box!Note: At first, I was hearing some crashy noises on the playback, but very quick it was ruled out from being the box, as the track picked up from previous noises. So to say this item did more than I actually thought it could ever do!I'm impressed indeed!Will recommend based on my on site impression!
