SABRENT 4-Port USB & VGA KVM Switch With 4 Sets Of Cables KVM-USB4

Pros: looks good

Cons: does not recognize Microsoft usb keyboard, nor logitech trackball, nor Kensington trackball,
Does not work, cannot switch computers, just does not function properly

Other Thoughts: The video comes on, but says that one or more of the USB devices has malfunctioned. I have used them for years, with other computers, other KVM switches, no problems, here not only a problem, they do not work. Video works for all 4 channels, can switch the video so I know it works, but nothing else, mouse, keyboard dead.

Pros: Great price. The three USB inputs are handy. No software or anything needed.

Cons: First off, the video output is a little fuzzy. It looks like the phase is out on the monitor, but it's not. I tried different monitors and adjusting the settings, but no luck. It just seems like the board doesn't have a very clean signal. Also, one of the monitor cables that came with it had an unseated pin. I think it may be barely out far enough to make contact with the mating socket, but I'm not sure. I have plenty other cables so I didn't even bother trying it.

Other Thoughts: Not an amazing product, but it does the trick. I run a computer service company and I only use it for switching between multiple computers I may be repairing at any given time. Because of this, the video quality doesn't bother me much, but if you are using this product on your main system, I hate to say it, but you may want to spend a little more for a better quality product.
