Due to space limitations I use one monitor for two computers on my desktop. The first one I purchased for myself several years ago. The second one I purchased and gave to a friend, who has one VGA monitor, an HP and an Apple Mac Mini. I have a Dell Optiplex and a Mac Mini. The two port switch works well for what it is designed for. I am very satisfied with this product.
I purchased this item with the express plan of converting it to a microphone selector switch for amateur radio. These switches are actually almost totally obsolete in the computer arena since USB but they make excellent mic selectors since they have multiple poles and 2 to 4 positions. I use one to switch between my hand mic, my headset and a boom mic. (a 4 position unit) and I use another one to switch the headset between two radios.
