Summary: They do have a responsive support, but they just claim that it isn't possible to support multimedia keys. I entirely fail to see why that is the case: the standard multimedia keys have defined key codes. There's no good reason why the switch can't read those, and output them again.
Pros: * Affordable * includes power supply so that you can attach a keyboard with built-in usb hub. * All cables included
Cons: Does not emulate basic multimedia keys! That means if you have a play/pause/next/previous buttons, or volume control on your keyboard, it will not work when connected to this KVM. That's entirely inappropriate for something that calls itself a "multimedia" KVM switch.
Summary: KVM implies keyboard, video, mouse. Unfortunately only the video is shared. You get to plug in the USB connection (very short - less than a foot long!) which I presume is one cable supposedly shared between the keyboard and mouse, however it doesn't work.
Summary: My wireless Logitech M310 mouse *almost* works. The buttons and scroll wheel work, but moving the mouse right to left moves the cursor up and down. Moving it up and down does nothing. Works find plugged in directly. Can someone tell me which wireless mice work? I'm not attached to this one.
Pros: Nicely built, good value, great features. Video looks reasonable.
Cons: Picky about mice. A wired IBM branded mouse didn't work at all (works fine connected directly). A wireless Logitech almost works (see below), a wired Dell mouse works perfectly. The Logitech m710 wireless keyboard/mouse doesn't work at all (as expected).
