Pros: none

Cons: Card is 4 port serial. When downloading drivers and auto selecting it keeps selecting 4 ports serial and 1 port parallel driver. Reboot and devices are gone. Will not accept drivers for 4 port serial only just the one with parallel and then doesn't work. Windows 7 64 bit. Syba really blew it with this product.

Pros: It's inexpensive.

Cons: I've installed the card, downloaded the software but the software doesn't see the card! I'll keep playing with this, but I'm not getting my hopes up. I have several other computers that I can try it on, and will do so if I can't get it to work on this one.

Other Thoughts: The driver disc that comes with this is absolutely useless. I do think it'll make a fine target for my M4, though!

Pros: I bought this for a laboratory instrumentation workstation. I had immense trouble using an older, much more expensive PCI serial card. This one worked smoothly and perfectly with default drivers. been operating well over a year now.

Cons: None

Pros: easy to install. works great.
But like the first review, download driver from Web site to install.

Cons: One problem I have is after windows updates that require restart. computer Stuck. remove card, let windows finish install. put card back all works fine.

Pros: easy to use

Cons: none

Other Thoughts: works great.

Use it as a console for routers and switches.

Download the driver from the company website!!!!!!!!!!!!!!!!!!!!!!!!

Cd drivers don't work.
