4 out of 5 eggsIt works!

Pros: Price
Compatible with the Belkin KVM cable sets I already had.

Cons: Did not see a way to chain together multiple units. Hot-key switching a little weird.

Manufacturer Response:

First, thank you for choosing IOGEAR and we apologize for your experience. I am sorry but the GCS78 is not capable of Daisy chaining or cascading. IOGEAR makes a variety of 8 port KVM's to suite almost all needs. IOGEAR has several 8 port KVM'S capable of cascading like the GCS1808. Once again, thank you for choosing IOGEAR.

1 out of 5 eggsBuy Some Other KVM Switch

Pros: It works, and it works well. I have owned this unit for 6 years now, and it is thankfully finally dying on me. I have cursed it every day of my life, but it would not die. The CONS are so serious that I WILL NOT BE REPLACING THIS UNIT WITH ANOTHER IOGEAR KVM SWITCH.

Cons: As my first review stated, the hotkey switching was developed by idi*ts. Having to enter 5 keystrokes with the last being the "Enter" key is beyond stupid. Over my 6 years of ownership I have cursed this KVM switch every single day after it shut down something I had just started on that machine when trying to switch machines. Still, it held in there for 6 years. Why is it when you hate something and want it to die so you can replace it, the thing refuses to die?

It is now on its deathbed. First, my primary work machine, running W2K, on channel 1 would not boot with the KVM swtich powered up (have it on a switch). It would hang during boot and I assumed it was hanging on either the keyboard or mouse. The machine would boot but only if the KVM were not on that channel and was also powered down. That has now a few weeks later progressed to where the mouse behaves so erratically that I can not work through the KVM switch anymore.

Yeah, the blinding blue power on light is another idiot feature. It took me 3 small squares of masking tape to damp it down to where it did not light up the room at night.

Like someone else said, I can't believe anyone at IOGEAR actually uses this unit. Wonder what brand they run in their server room, anyone know?

Other Thoughts: Lets just say that when I replace this unit, in an hour or so, with a new purchase from Newegg, it WILL NOT BE WITH AN IOGEAR KVM SWITCH. I love the fact it worked, and worked well for so long, but I absolutely hate the idiot hotkey sequence, and will be buying some other brand of KVM switch this time around. I flat don't care they finally woke up and fixed the hotkey problem, I won't support them ever again.

Manufacturer Response:

First, thank you for choosing IOGEAR and we apologize for your experience. I will forward these comments to the product manager for his review. Again, thank you for choosing IOGEAR.

5 out of 5 eggsExcellent KVM

Pros: This KVM is an excellent value, especially under $100.00
We have 3 of these in our shop, all of them work without issue
This comes with cables!

Cons: Yes the hot keys are goofy but if you hit them in order instead of all at once, they work like a charm
The enter key is a killer though, sometimes it does stop something accidentally on the screen

Other Thoughts: I would highly recommend this product to anyone at this price point
It comes with cables!
Also I do not understand the gender issues with the cables that people where talking about? No issues here?

5 out of 5 eggsWorks for all OSs

Pros: Unit handles Win2K, WinXP, and Win7 KVM protocols just fine. Direct switching is smooth from PC to PC. Nice little confirmation beep every time a channel button is pushed. Has worked on all screen resolutions tried so far. Unit runs cool, super low power consumption. Best of all it's 1 RU high with rack ears to mount in my rack! Comes with all the cables as advertised. You get 4 - 6 ft. cables and 4 - 10 ft. cables, which worked out great in my 6 racks, I didn't need a single extension cable set.

Cons: Uses a Wall Wart power supply. It would be nice to put the supply in the chassis. Hooking up all the PCs is very tight, they could have spread out the connectors a bit to take advantage of the entire backplane. Blue power LED is way too bright, I used one of the little serial barcode stickers (which you have to apply yourself) to cover it up. It still shows through, but isn't blindingly bright. Have yet to determine what the lifespan is of the unit.

Other Thoughts: We had two 4-channel units, cascaded together. Which worked OK. You had to scroll through each computer to get to the one you wanted, and one input was used by the secondary KVM switch. As long as they were powered, they were fine, but sometimes the power connector would fall out of one and the chain would break. But the last straw was when a Win7 OS was introduced on one of the PCs connected to the old units, it caused every computer to go wacko when the mouse was moved. I researched it and found Win7 KVM protocols were different than previous incarnations of Windows, therefore a new KVM switch was in order. This Iogear unit meets the price point required and since the cables are supplied, it's a downright steal. Even if it only works for a few years, it will have paid for itself.

5 out of 5 eggsPERFECT!!

Pros: I purchased this unit for a 4 server + 1 workstation rack assembly. I have 5 machines plugged in always, and one extra KVM cable hanging out the back of the rack for use when working on repair jobs or if I need a laptop plugged in, or whatever. This unit worked perfectly. It is internally powered (with an AC brick adapter), and has push buttons on the front for selecting your desired machine. It also shows link status, which is great. It is running flawlessly at 1280x1024 on Red Hat Linux machines.

Cons: The 'male' VGA plugs are a real bummer -- so I had to get 8 'female-to-female' 15 pin dsub inline adapters (because all my KVM cables have 'female' ends. Anyway - I'm not taking any eggs away... do you know why? Because there aren't many (if any - this is the only one I found) KVM switches out there for 15-pin d-sub VGA and PS/2 keyboards and mice. In a server environment, having PS/2 keyboards and mice is an absolute must -- many will argue with me that it is not, but when you're having problems, the first thing that drops out is USB via HAL. Ever try CTRL ALT DEL with a USB keyboard on a locked up system? Or, in Linux - try switching to the next TTY with F2, F3, etc... it won't work -- PS/2 is a direct serialized connection, and makes my life easier.

Other Thoughts: I would absolutely buy again - I don't care that it's a few bucks more than other options, it works great and its exactly what I wanted.

1 out of 5 eggsthe WORST kvm switch, ever.

Pros: It has a metal case.

Cons: Stay away, you've been warned. Why make the keyboard combination Ctrl, Alt, Shift, 5, Enter if someone wants to switch to CPU 5? Why not make it Scroll, Scroll, 5? Really? No, really? I read the reviews before I purchased this KVM and thought, how bad could this combo be? The complainers must be babies and be mouse people. Well, I use my keyboard for practically every function I do and sometimes the combo works, sometimes it doesn't. When it doesn't work, the only keystroke that registers is the Enter key and depending what you have open, or highlighted, it will receive the Enter command when you try to switch cpu's. ARGH! I have to switch via the kvm buttons about half the time I try to switch cpu's. I also had to put black electrical tape over the blue power light as it lit up my entire office. What a joke.

Other Thoughts: I can't imagine the guys at IOGear actually using this thing.

Manufacturer Response:

Thank you for choosing IOGEAR and sorry about your experience. GCS78 is one of our older version of our KVM, our newer version for example, GCS1808, uses [Scroll Lock][Scroll Lock][5][Enter] to switch to port 5. A little simpler than GCS78, but in the mean time, we want to make sure it’s hard enough that no one can switch port by accident. If you have any further question, please feel free to give our tech support a call at 1(866)946-4327 and we would be glad to assist you. Once again, thank you for choosing IOGEAR.

4 out of 5 eggsgreat KVM for the price

Pros: Mine has been working perfectly with 8 computers for the last 3 1/2 years. I only use the buttons, not the hot keys.

Cons: Will not work with the newer wireless mice; particularly the Microsoft 5000.

Other Thoughts: I have called iogear support once. The individual I spoke with had very little product knowledge. I doubt that I would call them again.

4 out of 5 eggsIf you already have KVM cables...

Pros: Nice, compact, mountable, rubber feet, hot key option

Cons: If you already have KVM cables like I did. typical KVM cables have male-to-male VGA connections. The inputs to this KVM VGA port are male also, forcing me to buy either the correct female-to-male cables OR female-to-female VGA adapters. That blue LED is way too bright.

Other Thoughts: Make sure you use power adapter that is included. Even though the KVM will power up and function correctly when connected to other computers without AC adapter, the video will be choppy and unacceptable

5 out of 5 eggsGreat value for the price

Pros: This is the second one of these I have purchased. The other was rock solid, so I figured why not buy another. Great unit for the money.

Cons: none

Other Thoughts: No, the beeps are not too loud and do not annoy me.
