Customer Reviews

good unit, but could be better
This kvm has the advantage that it only needs one single usb port on each of your pc to work. I connected a set of usb mouse and usb keyboard (both microsoft) to the kvm, and all was recognized with no problems. The audio quality is very good. When you switch, there's no beep sound (for me this is good). Also this kit doesn't need ac power adapter, however, there are some disadvantages that can be a deal-breaker for some. It inclues:
-if you have one linux box, the hotkey doesn't work and you need to push the button on the kvm to switch between machines. No big deal.
-when you switch, there is a delay, ie. you can't use immediately the keyboard and mouse, I guess that is because they need to draw power from usb port. This delay is about 5 secs long. I'm used to it now.
-on my windows vista box, I have installed a winxp virtual machine, and when I'm starting this virtual machine, the kvm switch automatically to the next pc connected. The same happens if I'm on Vista and focus back to the vmware window with xp. This is very annoying and the reason I give it 4 stars, because I use virtualisation all the time.
To sum up, this is a good solid and reliable unit, and supports usb devices, very popular nowadays. The price can't be beaten, so if you don't mind the little cons, this may be for you.

Works great with Windows and Mac
I've had mine for about a week now, and it's working great. Does exactly what it says... switches smoothly between computers. With Windows, switching is a bit slow because it takes a couple of seconds for Windows to recognize the usb devices each time. It's a lot faster with my Mac... switching is almost instant.

My only complaint is the physical design. When connected to 4 computers, the cables are sticking out all four sides. This makes this huge glob of cables, and makes it almost impossible to set on my desk. It would have been nice if all the cables plugged into one side. For this reason, it gets 4 of 5 stars.

Works well for the price
First off, this is probably one of the cheapest 4-Port USB KVM switches out there so you cannot expect the same performance of one that is 4 times the price. It comes with all the cables you need. In general, it works - I have 3 Windows XP PCs attached to this with a USB Keyboard and USB Mouse. The hotkey works quickly and for the most part it switches within 3 seconds without any problems. Rarely, the switch stops working and I have to unplug all the connections and reattatch which is annoying. I do not use speakers on my PCs so I cannot speak to the audio switcing. I agree with other reviews that the design is stupid because all the cables come out of the 4 sides making it a spider mess of cables. Other than that, it's a good budget KVM.
