Pros: Very easy to install. Worked flawlessly on our old fax server. Windows XP Pro SP3

Cons: No cons yet

Overall Review: We setup a PC as a fax server and would get corrupted faxes from some of the hospitals that were sending reports to us. Our software vendor said that this was one of the best USB modems for faxing. I installed it in the server and it solved our issues. Every fax seems to be coming in fine now. No corrupted faxes since.
