"Never had a problem, does everything I was looking for!"4.0 starson by MysteryLover379
Pros: I use mine primarily to carry almost all my files (especially my 60+ gigs of music!) since my old laptop HD is much too small.
Cons: I have no complaints at all. In fact, I liked mine so much I bought my boyfriend one just to take his music to work (yeah, same 60+ gigs).
Summary: It works great to take files back-and-forth from work and my freelance gigs. Also functions as a great back-up device for my laptop files. I'm looking at purchasing a pair to use for rotation back-up of our server files where one can be taken and stored off-site every other week and the other left for incremental back-ups throughout the week. They're easy to use, the software is adequate for quick-and-dirty incremental and full back-ups of everything, and they're small enough to grab and go. I don't use the one-touch push button, I schedule stuff to happen when I'm not using the computer.
