Great piece of equipmentSep 12, 2009
This thing works. I am an amateur radio operator (ham operator) and I used an old 486 computer to run several communications and logging applications in my ham station. The applications control my equipment -- changing frequency, logging contacts, sending/receiving Morse code, teletype, and other modes. When the old computer crapped out I had a real problem: The old computer had lots of COM ports -- new computers have only USB ports. I purchased two different USB-to-serial adapters -- neither of them worked reliably. I was a bit reluctant to pay the price for this one but, after reading the comments, I bought it.
This thing is great -- it setup in seconds. I connected my equipment to three of the four ports, set up the ports in Windows XP Device Manager (had to set the baud rate), started my old applications and everything worked perfectly.
Nice serial adapterAug 20, 2009
Product works as advertised. I am now using two of the four ports without a single problem.
For those looking for a USB to RS-232 Adapter, I would strongly suggest buying this one!

Keyspan usb-serial adapters superior to othersOct 09, 2008
I bought both the 4 port Keyspan USB-serial adapter and the single adapter after trying IOGEAR versions. I had various software issues with the IOGEAR when switching ports or plugging in different devices, as it would constantly assign a higher port number. I can only think it is a result of its incompatability with Windows XP (in the fine print of the instructions). The Keyspan USB-serial devices have worked extremely well and can easily switch ports. The difference is huge.

Reduces ClutterJun 20, 2008
I have used Keyspans individual port adapters for several years. They work flawlessly and are quite fast. I do a lot of work on high speed serial devices running without flow control. The devices keep up.
I found that I often had 4 single Keyspans cluttering my desk. I wanted this device. When I finally found it, it was a no-brainer. It works flawlessly. (I had hoped it would be less expensive than 4 singles - and it is - just a little.)
A nice little benefit is I use their static mapping tool to make the ports appear as COM11 thru COM14, eliminating past confusion about which port goes with which device.
Serial is officially a legacy device. New PCs don't have serial ports. But, if you have a lot of serial devices to manage, this is a great way to simplify cabling and management hassles.

Keyspan adapters are coolJun 17, 2008
I have used both the dual port and 4 port Keyspan adapters in a Mac OS X environment. Not much to say. They just work. Driver install is simple and creates appropriate /dev/tty... serial ports to access them. I've used CKermit in a terminal window to access the serial ports, and I've used screen (which comes pre-installed in Mac OS X) in a terminal window to access the serial ports. That has the added advantage that I can share the session. [...]
