Pros: easy to use easy to install small and not ugly vertical so it takes up less space on my desk

Cons: have not found any yet.

Overall Review: easy to install and use, because you plug it in and it does everything else for you and automatically backs up everything as you create it, save it, or change it. I originally bought this because my lap top hard drive sounds like it is going out (it has not yet) and I wanted a way to save my companies' data before loosing it. I also wanted to save my millions of images that I love to take. It saves the files everytime I make or change them, which is great so I do not have to manually do it, as I would forget. I was a little scared that it would take forever to install and be all complicated, but you just plug it into the USB and it walks you through the REALLY short install and that's it! Took about 5 minutes or less to get it out of the box, installed and all set up. I leave it on all of the time.
