Query: What have I been waiting for- this is great.

I was using a parallel zip 100, and transporting it and it's power supply back and forth. With the USB powered, ultra-lightweight zip drive, my solution is now completely portable and hot swappable-- making my life as a writer on the go so much easier! The only downfall is that it may have a long-term effect on the life of your notebook battery, if indeed you are using it with a notebook. But, I fell that the convenience is well worth it. I do recommend this item!
