Summary: Was looking for a good solution for a 3 computer setup I had which was connected to two 2560x1400 monitors. Worked great for about a month and then my keyboard started malfunctioning. It took me going through a couple keyboards to realize it was the switch and not faulty keyboards when I ended up using a brand new one on another computer and it worked fine, but went nuts adding random keypresses if I plugged it back in to the switch.
Excerpt: I work with two Kubuntu 12.04 Linux workstations continuously connected, and a Windows 7 employer's Lenovo 530 laptop that I connect every evening on returning home and disconnect every morning when heading to work (via a Lenovo docking station continuously connected). My monitors are dual Dell 3007 2560x1600 dual-link DVI, keyboard Avant Stellar (PCI connector via USB adapter), with a Microsoft wireless mouse.
USB in the Console intermittently resets itself after only 4-5 months of use

Summary: I purchased this item on December 29, 2013 and it was delivered on New Year's Eve--just in time for me to connect my 4 computers to my brand new dual 24" monitors . . . everything worked fine, until about a month ago, I suddenly lost mouse and keyboard control while working on my machine. Over the next few days, I discovered that this happens on all the machines, and what I noticed was that I lost both mouse and keyboard control--the lights on both would just go out.
Summary: Brilliant ordering from the States saved me a lot of money as the UK prices were too high. only potential problem is the power adaptor, luckily I had a spare 1 from the 2 Port Dual View I replaced :)
Summary: I have a dual monitor setup with Samsung and Dell monitors, Razor mouse, and Logitech keyboard. With 2 Macs that support single monitors, and two PCs that support dual monitors, this KVM has worked flawlessly. The device and cables are well constructed and provided excellent connectivity to all computers. I have no issues with video performance with desktop applications nor graphic intensive games running at 1920x1080.
Works very well with Lenovo W530, Dell T7600 and Optiplex-745 and two Dell 3007 dual-link DVI monitors

Summary: My setup consists of a Lenovo W530 laptop (Windows 7) in a Thinkpad Minidock Plus Series 3 - 170W, Dell T7600 and Optiplex-745 workstations (Kubuntu and Ubuntu 12.04, respectively), two Dell 3007 2560x1600 dual-link DVI monitors, an Avant Stellar keyboard (via Belkin PS2 to USB converter), and a Microsoft wireless mouse.
Works great but my fancy mouse had to plug into the front USB slot

Summary: The product works great. However, I have a Razer Deathadder mouse. In order for it to show up on any of the computers I needed to plug it into the USB 2.0 slot on the front of the switch. It's just a minor annoyance.
Excerpt: This is the best KVM that I have ever owned. It works very well for two monitors. I game with it and I do not notice any video or audio degradation. Computers boot better on this kvm than any other kvm that I have owned in the past. Hotkey switching has worked perfectly after getting a wired keyboard; wireless keyboards are not supported. It is a large unit and it is under my computer table. I have never had to reach under the table to correct this kvm.
Pros: Easy To Set Up, Reliable connection, Smart Features
Summary: The left control key on my keyboard sometimes doesn't register key presses while using the "keyboard only USB port" so i can't even use asynchronous hotkey switching to control the device. That was maddening until I finally ditched the asynchronous hotkey switching for a working "normal USB" keyboard connection. The speaker channel "bleeds" into the microphone channel. The microphone has "interference" like a loud rushing sound.
Wireless keyboard/mouse both work fine with emulation. If you're having problems you may have an old/unrepairable GCS1644!

Summary: I purchased my GCS1644 from Amazon.com in April 2013. I was using a Logitech DiNovo wireless keyboard w/ wireless mouse combo. I was unable to get the mouse to work with emulation enabled in the GCS1644. With mouse emulation disabled the mouse worked fine, but of course I got the annoying device attached/removed sounds and associated delays. No biggie, but irritating. What's worse is that the keyboard behaved flakey.
