This thing also has very low system requirements. I have purchased 3 of these for my systems. I have never had any problem. Speeds were excellent. It is a PCI winmodem that is made by DSI, the same people that make Creative Labs Modem Blaster modems.
Installation is painless and easy.
To sum it up, I am pleased with this modem over the VERY overpriced USR 56k Sportster Internal. Corp. All Rights Reserved.
