Not top quality, but get the job done for the price.

Summary: These are decent when they work, I had one that steadfastly refused to work correctly that I returned and got a replacement for (the return process was fairly painless). I am using them in a 2 monitor setup to switch between a docking station for my work laptop and my PC. The problem with these is that they don't do well when both DVI connections are not connected to a video card of some sort.
I sure would like a unit that works during BIOS Post

Summary: I am still looking to replace this unit. I have had a couple of problems, and tech support was not able to address. The keyboard on one of my machines, a new HP Envoy, does respond during the BIOS post. That means that I can't enter the BIOS, or boot from a device that requires me to use a keystroke to boot. (I tried every combination of attaching to the unit, with the same results. Trust me I tried every combination.) The video has worked on both computers.
Summary: If you want great sound quality through a KVM, get a diferrent one. If you dont mind a little distortion, this one will work pretty well.
Pros: Works relatively well for intended purpose. The switch works good; a little twitchy sometimes, but mostly good. No problems with video quality or general function after more than a year.
Cons: There is interference in the audio. When crank up the speaker you can hear the rice krispies snap crackle and pop. The audio line, USB and DVI are bundled to gether and obviously go through this very small box. There is insuficient sheilding to account for all the EM traffic bottled up there, thus the sound issues. I ran an independent line from the speakers to the computer and what do you know, problem solved. But this defeats 1/3 of the purpose of this KVM.
Summary: It functions well when it functions correctly. The push button switch is nice to have but it doesn't support audio via dvi and the cord themselves are pretty short; barely reaches my desktop of the floor and my laptop on the desk on the opposite side of my desktop.
Summary: I wanted to connect my spare Apple 17" Studio Display to my Mac mini (using an Apple ADC->DVI converter), *and* be able to use it as a secondary external monitor for my Retina MacBook Pro (using Apple's mini-DisplayPort->DVI adapter). Works like a charm (once I remembered to plug in the USB cable for my rMBP)! Had to go through the "unrecognized keyboard" process on both machines (which took all of 15 seconds), but after that, it's all working as desired/expected.
Cons: Either DOA or incredibly incompatible. Hooking this up causes one of my machines to fail to even post. The other can post, but when it starts booting into Windows, the display goes blank and claims it cannot display the video. Both of these machines work fine with another DVI KVM I have, and both boot fine without the KVM, so it's not them.
Switching works good but does not maintain video presence.

Summary: Switch works as advertised, Keyboard and mouse switch flawlessly between systems but it does not maintain video presence on the disconnected monitor. I use 3 monitors, 1 each connected to 2 PC's, the 3rd I use as the second monitor between the 2 PC's so that each PC runs in dual monitor mode. When I switch from PC1 to PC2, PC1 now thinks it has only one monitor/desktop and everything from the 2nd monitor desktop migrates to the 1st completely re-arranging the desktop.
Cheap Price, Cheap switch.... you want quality, then spend more money.

Summary: It's not bad for the price you pay. Take a look at all the models of DVI USB 2 port KVM's. Why is this one only $65 and others are $200-$300??? This one does NOT have active simulated monitor, mouse, or keyboard support. It is just a switch. Nothing more. The ones you pay $200-$300 for the same thing. Will have signal isolation to reduce noise, as well as active simulated connected monitor, mouse, keyboard capability. This isn't the greatest KVM switch.
