Does what it's suppose to do.  you'll need to download the windows 8.1 drivers to get this to work in windows 10.

Was a bit concerned when I ordered this that it would not work on a Windows 8 machine.  It was not plug and play, had to use the supplied disc but it did work.  I needed to provide modem communication for the programming and editing of data for a telephone door entry panel.  Once I got the right driver installed from the disc it worked great.

It is a great product. The software that it came with did not work as well as the built-in windows 8 software, but after I made windows run the device, it has worked flawlessly.  A good product for the price.

It works great. Just plug and play.
I was worried that it might not work with Windows 7 but it works great.

Purchased for installation of W8. After connecting to computer, I initialized it via Disk Management, and installed W8 easily.

The only issue was getting the drivers to install correctly with Windows 8.1. I would post the steps that I used, but I tried several methods and I cannot say for certain which method worked for me.

With windows 8 it works as plug and play with no need to use the driver disk or anything. Web pages and download speeds have increased dramatically from my old wireless usb adapter.

laptop is great, windows 8 is tough to get used to but that's not the laptop's fault.  Worked great right out of the box

Migrating from XP to Windows 8 has some challenges.  I decided on a clean install that required about an hour with Microsoft Support via telephone but all is installed flawlessly with no problems to report.

Worked great once I figured out how to make it work with Windows 8.  All you need to do is go to their website if you are having trouble getting it to work to get instructions on how to use it, depending on your operating system, but there call in support person I talked to was great.

In my quest to find a card that works well with Windows 8.1 and has good performance - I chose this card.  Overall I'm happy with it, although out of the box it would not work.  You have to change the jumper settings in order to get the card to work depending on your configuration.  Not a big deal but something to be aware of.  Read the manual!

Initially I got great performance from this card, several hundred MB/sec transfer speeds (copying from SSD drives).  Overall its leveled off and I get varying levels of performance out of it.  Its not the best card out there, but its not a bad option either.  It does not have RAID support, but it does have port multiplier functionality so it works with my external drive enclosure.

I'm using Windows storage spaces to enable some limited RAID functionality and so far I'm very happy with the performance and functionality.  No driver issues with Windows 8.1 either, but download the latest one from the website, go to the chipset makers site and get the newer driver, not from the card manufacturer itself.
