USB to Serial Adapter (RAT) TESTIMONIAL

This adapter in both of it's lengths is extremely easy to set up and install. Simple plug and play recognition and hot plug compatibility make this usb adapter a great data transfer tool for legacy devices. So compact that it basically hides itself in the pocket of your laptop carrier or briefcase. Versatility between serial devices being used such as modems, digital camera, printers and more. Personally I used this to upload some sample images to my laptop because it doesn't have a serial port which is what I need if I'm going to use my camera, especially while traveling. I'm no longer reaching around my desktop to find the serial port, buy leaving this plugged into the the USB port of the computer I save myself both time and hassle with cable connections.

It's my opinion that either the 7 foot or the 12 inch model depending on your use for it would be a great item to have on hand if for nothing else to give your existing equipment more versatility and easier connections.
