I've written other 3COM/USR opinions on this site so if you've read them you'll know how I feel in general about ther kit :- Expensive but generally worth the money in terms of support and quality. (Winmodems aside!) This product is no exception to that rule. The cost is indeed up there in comparison to other endors but the package you get in as good as you'll get. Card, cables, excellent manuals, drivers and a lovely shiney box. Installation is a doddle, or as much as a PCI card can be, and the drivers worked after a fashion on NT. In terms of operation the system works just the same way as a standard modem but connects a lot quicker and runs a lot faster. Performance when connected was as good as the ISP used at the time. The card itself performed well and didn't suck up too many system resources when running. All in all a very capable product, if a little steep on price.
