Summary: I'm actually using this only for input devices (keyboard/mouse) and analog audio, as my monitor is sufficiently high-res to require dual-link DVI or DisplayPort inputs to drive properly. Even in this role, it's less than perfect: - One of my systems doesn't boot correctly if the emulated keyboard/mouse devices are the only ones present during BIOS POST; I need to switch over to that host (and reboot, if it hung during a previous attempt) for the system to complete its...
Summary: EDIT: After contacting IOGear support, I was informed that the product no longer supports the keyboard shortcuts that I stated weren't working for me below. I'm deducting a star for that. Purchased this KVM after buying a less expensive one that didn't work well to switch between my linux desktop and laptop/docking station. Eventually found a blog post that mentioned this one works, which is the case. Switching takes a couple seconds, but is acceptable.
Summary: The pros for this item is the ease of setup for the novice user, and the ability to switch the audio. The cons are 1) you must use the supplied custom cables - if you are replacing a switch or want to use cables already in place, this is not the switch for you (the custom cables carry keyboard, video, mouse, and audio signals).
Excerpt: I now run four computers off of my 60" LED smart TV via wireless keyboard and mouse, and I can toggle between them quickly. All cables are included, I just plugged everything in and it worked great.
Summary: Very impressed with this product so far. Using it to switch mouse/kbd between a FreeBSD machine and a linux machine without switching the video. It works well and switches quickly. The mouse works on the FreeBSD console. Many of the negative reviews seem to be from nontechnical users who didn't understand the directions. I think it's a great product.
Summary: I bought this product through my office. We were looking for a 4 port KVM switch for several test systems we have. If you hit the wrong key on the keyboard, the "error recovery" takes forever (several minutes--maybe up to 10). Switching between the different systems requires a long sequence of key presses and if you press them in the wrong order, the switch goes into "error mode" again. It was pretty much useless right out of the box.
Excerpt: This KVM is small and works well. It is thoughtfully designed with the number 1 and number 4 computer cable attached to the KVM and the #2 and #3 KVM separate. You plug 2 and/or 3 in if you need them and just store the cable if you don't. This reduces clutter as you don't have extra KVM cables dangling from the unit if your not using them! I gave this KVM a 4 star rating only because I have a problem using it with my Mac Mini computer.
Pros: Easily Expanded, Easy To Set Up, Fast, Reliable, Well designed
Excerpt: How you use the product: I use it for my multiple desktops I want to network and simplify the uses for them, which this product is fantastic for! I use it to network my printer and fix clients computers which makes this a great tool for that. Things that are great about it: 4 connections is perfect for connecting 4 computers.
Pros: Easily Expanded, Easy To Set Up, Fast, Home and Personal Use, Reliable, Small
Excerpt: I already reviewed this product before receiving an offer to do it again after a week. This unit is now worse; mice or other pointing devices lack power - behaviour is a little awry - like only one scroll wheel working on the PC mouse, while the Mighty Mouse scroll ball does not work - even though by itself the Mighty Mouse works! Boosting power with a hub only works for the mouse port, not the keyboard.
