OLLGEN 2 Port USB 2.0 Sharing Manual Switch Box Hub 2 PCS Share 1 USB Device for Printer Scanner Camera Keyboard (2 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 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.

Did not last

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 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.
