My disk worked for 2 months and then stopped. After calling their help/tech number, I was informed that it was a goner. I now have to send it back to them and they will send me another one. In short, I am very angery. This thing was promised to be the answer for all my failed disks/zips. It is just as, if not more, unreliable.Think of it: There are 14 reviews of this product. Three claim failure. Can we conclude that one out of every 5 fails? Probably!
