Summary: Audio, and Video cable are about 3 feet long.
Pros: It works flawlessly. Seems to be quality construction. The included cables are quality too. Supports up to 2048 x 1536 resolution. Option of listening to one computer while viewing other. Switches very quickly, as long as the computer you're switching to isn't asleep. No problems waking the sleeping computer. I get the "device connect" "device disconnect" sounds from the computers when I switch.
Summary: I use KVMs daily for office and home. This brand has held up for me at least as other models I have tried at this price (tried DL_nk, IOm_ga, Trendn_t). It offers few bells, it switches, it works on Linux. I keep buying this linkskey model, cause it works well (until it finally pukes). I order a new identical model, unscrew failed unit from old cables, slap new switch onto the old cables. Then I throw away failed switch, along with box of new cables. sweet.
Pros: its 20 bucks. it works. this model consistently work for me for a couple of years of constant and daily use. works well on my VGA setups. I will likely buy another, again.
Cons: these things do fail, with constant usage. I tend to burn up and replace one of these every few years. usually one of the two usb ports will completely and permanently fail to register an IO device. I have not bothered to crack one open to learn what is failing. for 20 bucks / 2 years, I don't much care.
Summary: The switching on this unit is very slow, especially the usb devices. The first one I bought stopped working after about 4 months - usb devices (keyboard and mouse)were not recognized anymore and Windows reported a hardware error. I got a replacement through the warranty and that one broke after about 5 months - same issue. Needless to say I'm getting a refund and not buying any more of these.
Summary: This kvm works great for me at home. Very similar to the more expensive one I use at work. This unit worked right out of the box. I hooked it up according to the diagram and it worked great. The hotkeys work good once Window's starts, otherwise, I use the buttons.
