Title: do not buy!
Review: I tried to hook up this KVM switch and struggled with the cable placement like everyone else talked about. And then powered it on and it started beeping. I had a wired keyboard and mouse plugged in. Didn't matter, still beeped. So I double checked my cables, and still it beeped. Then I switched the mouse to the keyboard side and it stopped beeping, however the computer now interpreted the mouse movements as keystrokes and every move of the mouse would type jibberish into any available text box. So now I have a 2nd mouse plugged into the keyboard port to stop the beeping and my main mouse is plugged into one of the alternate device ports. This product is so incredibly bad. I wouldn't even expect this out of a knockoff.
Is this product review negative?
