KVM Switch VGA 4 Port Auto Scan VGA Switch Box with Audio and USB HUB Output Switching by Button/Keyboard/Mouse

I bought this USB KVM switch earlier this year and found it to be unreliable. I have 2 Quad PC's & 1 i7 PC connected to this switch and find it regularly freezes, or crashes every time I use it. I have also tried to use the hub to switch portable usb hard drives between these PC's with the same results.How ever the company contacted me and offered me a newer version (free of charge) which I have now received and used with very reliable results - the switch no longer freezes or crashes even with the same PC's and hub connected. I have been using it now for nearly a week and I can honestly say that it has been totally reliable.I am grateful to the company for their efforts and really pleased with this result and would now thoroughly recommend this KVM switch to anyone.

bought this as a replacement for my old KVM. This one is usb and works perfectly. No regrets. Highly recommended.
