56k USB Modem Review

Ryan - 11/25/2009 2:15:44 PM

Pros: Very easy to use. just plug in the modem and play the driver. follow the directions, and your up and running. Doesn't take up alot of space. Also COMPATIBLE with Windows 7 32 bit. Don't know on 64 bit because i haven't tried it with that yet.

Cons: Would be nice if it came with instructions that had a troubleshooting guide in case there was trouble, and listed it's specs and operations in a more defined manner.

Other: For $16 it did exactly what i needed to do. In fact,it did what most others 30, 40, and 50 dollar modems do. Really good deal if u have dial up and just need a modem for the connection.

Pros: Inexpensive...Works well, found by uindows 7 and all is well. The next best price was sears for $20 oplus shipping and then Microcenter and the like wanted $50 for similar products. Stinks that they don't include modems in newer laptops when you want to fax, dial-up (if necessary).

Cons: none yet!

Other: Fast delivery. Fantastic Price!!!

Works with Windows 10, installation happened before I got from the back of the computer to the front. Operation was letter perfect from the outset. Great value.

Will this modem work as a replacement modem if my built in modem is no longer working?


That is definitely one of the reasons this modem was made so that you could get on the internet with a computer that does not have a 56k modem in it or for a computer that had one but stopped working.

Does this product with the Vista 64 bit operating system? How about Windows 7? If both answers are "yes" I will buy one. Thank you.


We do have drivers for Vista 64. Since Windows 7 hasn't officially been released, we don't have full support for 7, but we have sucessfully used the modem with the existing drivers in Windows 7
