Sommaire: I upgraded computers from an older model that had a built-in fax modem. I still have occasion to send faxes the old fashion way to a client. This USB dongle was recognized by Windows 7 as a fax modem when I plugged it in and worked right out of the box with no fancy installation or anything.
Sommaire: Shipping was on time. Unit worked out of the box as expected. Software leaves something to be desired but with Windows 8 I don't use it anyway. The fax package in Windows 8 hooked up with it immediately. Took me 10 minutes to set the whole thing up and send the first fax.
