Pros: If you need a PS/2-to-USB converter to use with your existing PS/2-style KVM switch and one of the newer motherboards with either 0 or 1 PS/2 sockets, then this is one you should try. Purchased 10 of these and they all work well between the two PS/2-style KVM switches I have and the 3 types of motherboards. The KVM switches tested are the IOGEAR GCS614A (for 4 computers) and IOGEAR GCS612A (for 2 computers). The converter worked well with both mouse and keyboard connected to it and with only the mouse connected to the converter (i.e., keyboard connected to the motherboard port). Never saw any lag in mouse or keyboard performance compared to directly connecting the mouse and keyboard to the system. Keyboard worked well when editing BIOS settings. Unlike USB-style KVM switches, there is no delay when you switch to/from the system with the converter.

Cons: Only one system had any problems with the converter (over reactive mouse) and that was fixed by rebooting the computer. Also, I have no idea how well this converter works without using a KVM switch (i.e., mouse/keyboard-to-converter-to-computer), because that is not why I purchased it and I did not test that configuration. Not a Con, but remember that some motherboards do not put out enough USB power to support adapters, USB drives, etc., so be sure to test the converter on multiple systems if you encounter a problem. I suspect that this is the problem encountered by others who have reported poor results with this converter. If you run into this situation, plugging the converter into a powered USB hub should fix the problem. I ran into this a long time ago on a Dell system with a Cables-to-Go USB converter and a powered USB hub fixed the problem.

Overall Review: Be sure to Enable/Allow Legacy USB support in BIOS. Also, make the PS/2 connection(s) before plugging in the USB cable, especially when you are hot-swapping (below) the converter. Unlike other converters I tested, you can boot with the converter and then unplug/replug the USB cable or swap to another converter (hot-swap). You can even boot without the converter in place and then plug it in. This converter seems to do everything I need or might need it to do.

Pros: I bought this because I have a IO Gear PS2 KVM that I was using with two PS2 computers. I replaced one of the PS2 computers with a Dell Inspiron 530 that only has USB ports on it. I was skeptical because I read many reviews on other PS2 adapters that do not work with some KVM's. However, in my situation, it worked perfect. The switching is fast and I have had no disconnection problems. Please note that this works great with my Dell 530 and my IO Gear KVM PS2 but may or not work with other brands.

Cons: None so far.

Pros: -It works on a MAC. I have been through three that supposedly do the same, this is the only one that worked. So now I do not have to spend another large amount of money on another USB keyboard and mouse. I am only in Linux on my MAC so I have no clue how it works on OS X but it should work fine! -Affordable solution to KVM and MAC problems similar to this!

Cons: It IS a bit bigger than expected but I really do not care at all. It's not much of a big deal. I would rather have something somewhat big and work than small and not work at all! The Cord size is a bit small but with some PS2 extension cords it should be fine. All in all, no big complaints and works right out of the box

Overall Review: My MAC never came with a keyboard and I did not want to spend another large amount, so I got converters and everything! All the others went back to the store and this was the last attempt before I had to cave in and buy keyboard and mouse. This has really been a life saver! I recommend this to everyone! I also want to add Neweggs super fast shipping. I ordered it Thurs. morning and was at my door Friday Morning. 24 hours! Thanks Newegg!!!

Pros: It just flat out works. And it's much cheeper than a new IBM USB KYBD. Nothing more to say.

Cons: Not realy a con, but it appears to like to have both the mouse and KYBD plugged into it.

Overall Review: I got this a while back when I replaced my KVM switch with one that had only USB and I wanted to keep by IBM PS2 KYBD. Works like a champ with both the KYBD and Mouse (using a USB to PS2 adapter) plugged into it and it plugged into the KYBD jack of the switch. Doesn't work as well with only the KYBD and the mouse plugged into the USB mouse port on the KVM suitch.

Pros: Works with my Linksys KVM switch. I'm running Windows XP and Kubuntu Linux on two Thinkpads.

Cons: Wish it was black. But, function is more important than color.

Overall Review: Should have purchased a spare.

Pros: Seems to work with just about any OS or platform I plug it in. Mainly got it for work on those ZBox/Net-tops or other Mfg. PCs that have only 1 PS2 port where an extra PS2 Y is needed for mouse/kb or only USB connectors are provided. Seems to be made fairly well, medium grade plastic. USB plug and PS2 ports look and feel decent when plugging/unplugging connections. (A little warning not to hot swap a PS2 plug on a mother board as it can short out your keyboard controller. ) USB is more robust and will allow hot swapping KB Mouse over a PS2.

Cons: Only comment I have here would be that it is slightly bulky (not a deal breaker though) but my guess it is actually has some electronic guts inside the wedge to make it work with a variety of systems providing for compatibility.

Overall Review: Been plugging away at systems since 1983, have had all kinds of gadgets through the years. This is a good tool to have in a computer arsenal for the quick and dirty times or just when you are in a bind and have a pile of PS2 KB and Mice laying around :) (Cheaper option than ordering mid-grade USB KB and Mouse ) Have not tried using PS2 KVM to USB systems but I would not be surprised if it worked well that way too.

Pros: Works as described, and works perfectly with PS2 KVM switch, so that will help with the motherboards that are changing to 1 or none of the old PS2 style ports, if you still have old components left that work and are worth using.

Cons: none

Overall Review: Highly recommended

Pros: Works with MANY devices, including Wii, MacOS 9 via USB PCI Card on beige Mac G3, and Linux

Cons: Drop keys like crazy, including forgetting to deactivate meta-keys on release if held down (see below)

Overall Review: (Typed directly with UPS2C adapter using Focus FK9200 keyboard without manual corrections to shw drops) have had drops with other keyboards, but this is the worst one. I thik the drop rate depends on how fast yu type. Most people usin wireless keyboards would have difficulty tellig if the keyboard dro would be due to the wireless commuication or the adapter tself. I hope this text is an illustration of the drps keys. did correct any mstypes I believe I made manually, so wat I said abve isn't completely true.
