5 out of 5 eggsSolid KVM Switch

Pros: Connected right up and worked right out of the box. I did not use any of the USB ports, so I cannot attest to how they worked, but everything else went right together and worked fine.

Cons: I would have rather had the PS/2 ports on the back of the unit, but that is just a result of how my peripherals are arranged. Having them on the front might be preferred for the next guy.

5 out of 5 eggsExcellent, versatile KVM

Pros: Works as advertised. Connects diverse computers with a mix of USB and PS/2 ports and devices (PC and Mac) without any issues. All cables provided. Optionally powered USB hub feature works extremely well. Physical and virtual switching via hotkeys works well. Highly recommended.

Cons: The manual is barely adequate, and the translations, although better than average, are still not great. As a result, getting it working the way I wanted took a bit of fiddling.

Other Thoughts: I was dubious about the claims made for this KVM, and couldn't understand how it could live up to them. For instance, the cable connecting the KVM to a computer has only a VGA plug on the KVM end, with VGA and two PS/2 plugs on the other. Apparently there are enough spare pins on a standard VGA plug to carry the two sets of PS/2 signals, because it works great. I also spent some time wondering how to connect a computer with a USB mouse AND a USB keyboard, when there's only one USB jack per PC on the KVM. I finally realized that the KVM acts as a USB hub, so that any USB device plugged into the KVM is seen by the connected computer, as long as a single USB cable is connected between the KVM and computer. My PS/2 keyboard is plugged into the console PS/2 jack on the KVM, and works fine via USB on all connected computers. This KVM handles my power-hungry USB gaming mouse just fine with the power adapter, something I was previously unable to do with previous KVMs.

5 out of 5 eggsSolid

Pros: I only use the PS2 Function, I have owned for 3+ years. It is still working with daily use on repair benches. Vigorous daily use. I am buying a second one because I damaged one of the cables. Very reliable.

Cons: None

Other Thoughts: FYI, I really don't use the audio function

1 out of 5 eggsDidn't work for me!

Pros: Keyboard, mouse & sound work great.

Cons: Will not pick up monitor. One computer would only give me a basic resolution. Another computer would not even pick up my monitor at all. This monitor and computer combos worked great on my Startech kvm, but will not work on this one. I RMA'd and tried another switch and got the same results. Returning the second one for a refund.

Other Thoughts: Might work for someone else, but didn't work for me.

3 out of 5 eggsHot-Key Support Misleading

Pros: Overall it's a solid device. While I don't use it, I could see the benefit of independent USB/Monitor switching. Comes with the cables which is a plus and they are long enough for my needs. A bit pricey but I guess supply/demand is more a driver for this.

Cons: There is NO hotkey support unless you are using PS/2 keyboard. Who has those any longer and why was that not indicated in the details/specs?

Other Thoughts: Again, not a bad KVM overall. Had the specs indicated hotkey support was for PS/2 only, I may have looked at a different switch. Luckily, I had one laying around and could use it to lock the synchronization of the monitor/USB switching which can only be done with the hotkeys.

2 out of 5 eggsPort 1 defective

Pros: Nice unit. I have a customer who uses it and likes it. I purchased it to replace another KVM.

Cons: One of the KVM ports is defective (checked cable, but port is bad). Very inconvenient! I guess I will drag out the old KVM one more time....

1 out of 5 eggsPoor quality cables

Pros: 4-ports, PS-2/USB/D-Sub/stereo_audio switching together or separate. Ability to reset KVM side PS-2 keyboard and PS-2 mouse. Cables included, but see Cons.

Cons: 3 out of the 4 combo video/PS-2 cables were bad. PS-2 keyboard and PS-2 mouse were not seen by the computer.
Very frustrating and time-consuming troubleshooting what the actual problem was. Very poor quality control on the cables. Instead of saving money, I blew a lot more in time in addition to the frustration and missing cut-over of new computer

Other Thoughts: Was driven to buy this due to purchasing a replacement computer having a motherboard combo PS-2 port that the old KVM switch didn't work with. Needed something that could switch USB mouse. The price was right and this probably would have worked if the cables had been good. Didn't have the time or desire to keep swapping out units waiting to get a complete good set of cables. Decided to move up to an expensive 4-port KVM that uses separate cables and switches DVI along with D-SUB, USB, and surround sound. Don't buy this unless you want to waste a lot of time and have to deal with replacing bad cables.

5 out of 5 eggsPerfect !!!

Pros: - Very straightforward and intuitive setup. Didn't even have to refer to the manual
- Worked perfectly with all my different devices and OSs.

Here's my setup:

- Win XP Pro desktop
- Ubuntu Linux desktop
- I plan to hook up a MacBook pro laptop and Vista laptop too !

Devices (always plugged in):
- Logitech Media PS2 Keyboard
- Logitech USB mouse
- Samsung 22" VGA / DVI monitor (used VGA with the KVM)
- HP 5780 OfficeJet all-in-one printer

Devices (plug in n out):
- SanDisk Cruzer 16 GB USB flash drive
- Seagate FreeAgent Pro 1 TB external hard drive

Cons: One minor con, although I found a great workaround, is that my Logitech SetPoint keyboard management software doesn't work with the switch, but I found a hotkey program (AutoHotKey) that works much better than Logitech SetPoint !!!

Other Thoughts: - Definitely worth every penny because it just works, no hassle
- Awesome shipping by Newegg. Chose EggSaver shipping (4 to 7 business days) but got it in 2 business days :)

4 out of 5 eggsDecent KVM

Pros: switches USB, Audio, PS/2, and VGA; with audio and USB possibly switched independently (unbinding audio requires PS/2 KB for hot keys).
Supports 1920x1200 resolution (and a little more, I think...)
Intuitive interface.
Includes all cables for everything.

Cons: Hot key functions require PS/2 KB to work.
PS/2 KB required if you have a machine that only recognizes PS/2 KB - the mfg write-up led me to believe that translation from usb kb to ps/2 kb would occur.

Other Thoughts: Seems like they should be able to make an old dinosaur like my NT box work with a usb kb... but I suppose it's really time to retire that anyhow...
