Yet again StarTech score the points. These days I barely look at other USB device suppliers, StarTech always seem to get the points.

This device is 4 inches long, and allows the user to hook up USB peripherals to more than one computer. the computers can then request use of the peripherals, and it will switch the control between the two. The switch can be controlled by software supplied with the control, or by the button on the top. this makes it ideal for remote use. The descriptions never seem to mention that you could choose to put a USB hub on the switch, and share many peripherals between the computers. This does work, I've tried it. I would ensure you use a USB hub with a power source though, seems a tough ask to expect the switch to support it all.

My only gripe is that when you request control of the USB devices from the passive machine, it doesn't put up any form of warning on the currently controlling machine. I would have liked a 5 second timeout on a Yes/No window. Maybe someone is requesting use of kit I'm in the process of using! Likewise I would have liked to see the option to lock the switch for x minutes, so if I'm using the disk drive that's attached I could set a lock for 1 hour and then the process could complete before anyone was allowed access. This could be fed back to the requesting machine, not available for x minutes, etc. Alas it DOES NOT DO THIS. So it's got some rather tedious limitations on that side.

However, it does the job and I do like it. It's solidly built. Light enough to Velcro on my machine.

Could easily do better, but very good.

This is nearly spot on for me, I have it connected to a USB hub and the switched leads go to to a desktop and a laptop. I can connect the laptop to my desktop monitor's second input and tap on the monitor change button, then on the USB hub switch selector button, and the keyboard and mouse switch over to the other system. Now I don't have to change position and keep finding myself typing on the wrong keyboard. It only comes with two leads despite having four ports, so you'll need to source two leads yourself.

I say nearly spot on because on one input, once it's on there it stays there and no amount of pressing and swearing will make it change to a different input. I have to unplug that input, wait for a bit, then change to a different one. Why it sticks on that particular input I don't know.

Does the job very well. Been using it for about a year now and it's never missed a beat. I use it to share a monitor, keyboard and mouse, hooked into a Dell D3100 dock, with a Mac Mini and various laptops. It works well.

I have three laptops and up till now I had Wireless keyboard and mouse for each laptop but this have slowly driven me insane with the clutter of three mouses three keyboards. I saw this item and it ticked most of my requirements. What I liked about it is there is no requirements for software just a manual switch to take care of things and no software. No one has mentioned anything about Wireless keyboard or mouse use so based on the review I bought the item.

Unfortunately the manual facility does not work when you try to use a wireless keyboard it is almost like a some protocol overides the manual switch facility avoiding you from manually switching it. This forced me to use the software and retain connection of the wireless mouses to use the software to force switch the KVM however here in lies the problem if you use a password or your PC have a power up password you will not be able to switch to PC manually.

If you have multiple wireless keyboard and mouse Combo's then you can retain their connectivity and add one to the KVM switch leave the rest in storage however you will still need the mouse and the software for each unit to switch the KVM. No good for job entended.

Cabling is well thought out and if you have the urge to have neat cabling then this unit is a definate buy. I have not tested it with with Wecam's or Printers but I guess it will work well it is now consined to if needed box

This product does not work with my high spec gaming mouse when the specialist drivers are installed for it. It hangs the OS (Windows 7). However, it does work with the windows drivers, which are just about good enough to pick up most of the buttons, although I lose the ability to program.

It is certainly better than the Digitus version I purchased, that refused to work at all (returned).

It also struggles when too many high throughput peripherals are being used. For example, I connected a USB3 hub with 2 display link adapters to it. This caused regular power blips to occur. I'm unsure at the moment if this is to do with the USB hub, or with this. I don't remember it happening before I bought the the sharing switch. As I don't use the display link adapters on one of the computers this is connected to, I have simply disabled the devices in that particular OS.

Sometimes it needs a double switch to pick things up correctly.

Overall, I've managed to get this to do what I want, but there is a rather long exception list.
