Summary: Using this on 4 servers and 1 PC. Switching between systems is actually fun: Scroll lock twice, scroll to the system, hit enter, and away you go. No more fumbling around for a KVM button to push and trying to figure out what system you're on. Video issues are somewhat annoying but with this being used primarily for servers I'm okay with. If this was going to be used with my home PC(s) it would be unacceptable.
Pros: Super easy to install, setup, and use. Fast switching between systems. Ability to label individual systems via overlay is sweet.
Cons: Some ghosting and video degradation. Blue power LED in front will blind you if you look directly at it.
Summary: I will definitely purchase another. I have used many KVMs over the years and looked at the offerings from many manufacturers. It was better to spend ~$100 more on this one than the least expensive alternative as I have been completely satisfied.
Pros: Responsive; versatile connectivity options; has the important configuration options expected; well built
Summary: if using it in a rack, I recommend using 10' cables. I am controlling a couple of servers using this device, one of which was rack-mounted. The cable-management for the rack unit used all but 6" from my 3' cable. This would work extremely well in a desktop configuration as well as in a rack like mine. Using other accessories, you can setup your keyboard, mouse, and monitor up to 500' away using a Cat-5 cable.
Pros: Intuitive OSD! Capabilities for up to 512 computers using a daisy-chain method! Smooth operation using either the OSD or the hotkeys on the unit. Has worked flawlessly for just over a month now. Supports both USB and PS/2 flawlessly. For extra security, it supports usernames and passwords to login to OSD before you can access the computers.
Cons: Documentation seemed a bit on the low side. If you have ever used a KVM before, you won't need it though. Doesn't come with cables, so you must purchase them seperately.
Cons: On my second one. Sent back the first one. The performance is good until it isn't--by that, I mean that certain ports will start to go skittish, and will respond only intermittently. First one port will go, then another. Sometimes, a hard reboot of the switch will fix the problem temporarily. Sometimes not. After two tries, I'm tempted to give up and try to get my money back. I may try one more time. Get another one if you can.
Summary: Great KVM to do multi-os switching. Completely simplified my life.
Pros: Using this KVM to switch 2 x64 boxes and also a OS X box running 10.4 and two virtual servers. To envoke the OSD and switch systems all you gotta do is hit scroll lock twice (this can be changed).
Cons: None. Guess it won't do HDCP. Very slight ghosting in x64. The OS X boxes look better and you can't see any ghosting.
Summary: I wanted this KVM switch but found pricing on other sites too far out of my department's budget. As soon as I saw it on NewEgg, I had an order placed and have been happy ever since.
Pros: I previously used two 4 port KVM's from another company. They worked OK, but this IOGEAR model is much better. I have a mix of Macs and Win2000 & XP PC's. All work great. I'm using a PC USB keyboard and the IOGEAR maps the windows key to the Apple command key.
Cons: Don't forget the necessary cables since they don't ship with the main unit.
