Rating: - A very good adapter based on Prolific chipset.
We have tested this converter under Windows XP, Vista on wintel notebook and Mac OS Leopard on MacBook. It worked very well. Overall, very stable product.

Rating: - Works out of the box on Linux
I needed this to connect to my SBC ALIX-based embedded firewall along with a null-modem cable. It works without a driver on my linux (Debian) system except to figure out the serial line I had to run $ 'dmesg | grep tty' and it shows up as ttyUSB0. Set this in your serial client connection software. I tested it with minicom and Putty which should be in the packages for your distro. Debian makes liveCDs if you don't have a *nix box.

Rating: - Does what it says, though a little clumsily (and not in Vista)
The small non-profit office where I work recently received as a donation one of those scales that will automatically calculate shipping rates -- if you have a serial port on your computer to load current rates onto the scale. I don't.

I was surprised to learn from reviews on various sites that it looks like all USB to serial converters have a hit-or-miss factor, but decided this one would be worth the gamble. It was.

It took some trial and error in when I connected it to the scale and the computer, and it did require that I install the driver from the CD, but it worked on my Dell running XP with all the available updates. So it gets four stars for that.

I deducted a star because it appears that I'll have to use the enclosed CD every time I use the cable. Not looking forward to trying to keep track of both pieces of a product I imagine I'll use only once a year or so.

Additionally, this converter did not work on another machine running Vista. No stars deducted because the manufacturer doesn't claim that it will, but still a downside, especially as it appears it's no longer possible to buy a new computer running XP. Boo.

Rating: - Great Item
This USB to Serial adapter worked perfectly. I was affraid it would not be as good as a true RS-232C output but I had no trouble. Would by it again.

Rating: - Worked Like a Champ
This product worked perfectly, and I have not had any issues with it whatsoever. After I installed the drivers, everything that I have used with it has worked without a hitch.
