Pros: This is one of the few options a Vista 64 user has for a dial-up modem. If you live where dial-up is the only option, and have Vista 64, this is the one to buy. This has been very reliable so far (a few weeks of constantr use) and it is simple to install (USB)

Cons: None. Just wish I had broad band available locally, but that's another issue..

Overall Review: I can see why people hate Vista. No drivers! At least this device is supported and works well.

Pros: It installs and works with no problems under Win7 64-bit. Since no other modem I know of does this as of the date this is written, that by itself is worth five stars.

Cons: None observed first few days.

Overall Review: A no-brainer if you want to fax from your Win7 machine. (Does anyone still use a modem to get online?) Sorry. I know some people do; but I have not tested it for this.

Pros: Small, compact. Works flawlessly. Used on Windows XP Pro platform. US Robotics is a very popular name brand and they are well known for their quality modems.

Cons: The CD ROM comes with a bunch of apps you don't need.

Overall Review: When installing, just put the CD ROM disc in, and plug in the modem. The driver files are kept in the root of the CD so when your computer prompts you to install the driver, just point it to seach your CD drive and it will find them automatically.

Pros: -Works in every GNU/Linux distro I've tried it with. (I chose this product based on the many other reviews, here and elsewhere, that noted it works in Linux. Many thanks to all of you.) -Makes and keeps solid connections at highest speeds possible (usually b/w 50,666 and 53,333 kbs, depending upon ISP). -Lightweight and relatively small.

Cons: Construction seems flimsy. The connection where the wire meets the rectangular box has come loose.

Overall Review: 1.) I can't comment on the "modem-on-hold" feature, as I have extremely limited experience trying it. ("Tuxcall" was the only Linux app I could find to use such a feature and I didn't get too far with it.) 2.) If Gnome-PPP (or whatever dial-up app you use) does not automatically detect this modem, just select or enter the modem location as "/dev/ttyACM0" (without the quotes) manually. (That's a ZERO) 3.) PCLinuxOS (main KDE and Gnome editions) and Puppy Linux are the only distros I have found where dial-up just works "out-of-the-box" w/out any hassles. If you can't connect due to a permissions error or if it disconnects right after connecting, try making sure that your user is part of the group "dialout" as well as "dip". Commands: (remove "s) To see users/groups: "cat /etc/group" To add a user: "adduser {user} {group}" (Thanks to "slider" at Linux Mint forums)

Pros: Small, quality construction, USR reputation, does it's job well.

Cons: Major: Windows 7 will not detect driver if left to its own searches. If you point the Windows Device Manager to the folder the driver is in, the install will appear to go well, but the install will be faulty. The symptoms of a faulty install are that everything related to the modem, even displaying its own Properties, is agonizingly slow. The software acts like the hardware is working, but the modem is unable to actually make a connection. However, if you download the latest driver from the USR web site, lead the Device Manager by the hand and point it to the actual driver INF file, the driver will install correctly and the modem will operate fine. Minor: Just by opening the installation CD USR will automatically install some of its own bloatware without even asking. This isn't a bug I suppose, just annoying since you have to go to the Windows Control Panel to uninstall it.

Overall Review: The modem hardware appears to be just fine once the software drivers are installed, but USR needs to work on their drivers so they are automatically detected and installed correctly under Windows 7.

Pros: This Modem is Just what the Linux doctor ordered! I've had perfect success using this with Ubuntu,Suse 10, PC Linux OS and MineMe. Thanks US Robotics for taking care of the Linux Crowd- you are much appreciated by this user!

Cons: Absolutely NONE.

Overall Review: I finally found a used modem that worked on the above Operating systems, but wanted a new & modern solution-this little modem fills the order with USB & no power supply needed.

Pros: No serial port required. Driver installed in Server 2003

Cons: WARNING! Do not try and use more than one of these on the same pc/server. They will not work at the same time.

Overall Review: I installed 4 of these on a HP server to use for Microsoft Fax server. First off, they failed to install when connected to a startech 4 port PCI USB card based upon the NEC usb controller. I gave up after several hours and connected them to the built in HP ports. They all installed OK and show up correctly in device manager and in the Fax Server Manager. However, I was getting complaints of faxing not working. I found thru testing that only the last modem connected works. If you unplug a non-working one and plug it in, it becomes the modem that works. When discussing it with a coworker, he told me he had discovered the same problem a year back and never got a solution. Hopefully this post saves someone else from this nightmare! oh.. and yes, i contacted usrobotics and no they did not return my emails or calls.

Pros: Small and easy to use. It installs and works with no problems under Win7 64-bit.

Cons: None observed

Overall Review: Only the modem I've found without conflicting while installing multiple modems on some computer.
