Pros: Works out of the box with any modern Linux distro as an earlier reviewer notes. Very easy to get up and running as you just plug it in and away you go.
Didn't experience any problems at all and have been using it constantly now to link a serial UPS into my Linux fileserver - no issues whatever.
 
Cons: The only criticism I have is that the USB plug isn't a very sturdy plug so dangling a serial cable off it on the end of a device like this can possibly put undue strain on the USB socket - it's no big deal and as long as you're aware of it it's easy to work round. A small extension cable bypasses this without issue anyway.
 
Other Thoughts: Great adapter, very cheap, makes it easy to put legacy serial devices on a modern machine without resorting to PCI serial cards.
 
Bottomline: If you're in need of a serial to USB adapter then this is a great little version with a reliable chipset supported by most platforms.

Pros: - Easy to setup, works right out of the box with any recent Linux distro and with the Windows drivers from the CD.
- Fully supports CTS/RTS and DSR/DTR signals, something that several other adapters don't.
- Extension cable is nice.
 
Cons: - Screws don't fit correctly with the case. Since they are male screws and I am using a null-modem cable with screws too, I ended up removing them.
 
Other Thoughts: Could not get it to work with the latest Windows XP 32-bit drivers from Prolific web site, version v2.0.5.111. Although Windows recognized the device, I always got a message telling that something went wrong while installing the device, ending up with an exclamation mark at the port in Device Manager. When I tried running the installer provided in the CD, first it removed the existing driver. At the second time it installed version 2.0.2.1, which worked fine.
If you need to download driver version 2.0.2.1, use this link from Softpedia: http://drivers.softpedia.com/progDownload/Prolific-Technology-PL-2303-Driver-Download-24876.html
 
Bottomline: Good adapter, just what I needed to talk to some RS-232 equipped routers.

Perfect for my power inverter!

Pros: Needed an "old style RS232" to USB converter. After some checking in computer stores (price around 25USD!!!) i found this one.
Works perfect. I leave the adapter all the time in the DB9-plug, so i can easily connect with the USB cable.
 
Cons: -Needs driver to work. 
-The supplied CD didn't work so i had to download from internet (uses common chipset)
-Package claims built-in LED, but actually no LED.
 
Other Thoughts: Very sturdy. Molded in transparent resin. This means that when he is defective, you can't open te casing, but why woud one for such a price!
 
Bottomline: buy.

Great for old parts

Pros: This is great for new computers. If you have an old printer, scanner or gamepad/joystick, this the ony way to use them. And with a very little cost. Also it has a extension cable. That is great. 
 What can u expect more?
 
Cons: I don't think this  got any cons. Maybe build quality can be better. But this time price will raise.
 
Other Thoughts: You can use it with Vista. Just download the driver. You can found drivers at forum where bottom of the page.
 
Bottomline: If you are looking for a RS232 to USB converter. That is what you are looking for.
