    I have one complaint though. The picture of the item on the website showed a USB port on one end. The item does not have a USB port.

    This product has backed up and protected my home office without incident. The only reason I didn't give it 5 stars is because I had the same device prior to buying my current device that died after only 2 years.

    I'm finishing up my Bachelor's degree in software engineering, but live in a rural area where the power tends to flicker at least once every time there's a storm. I hate having to constantly save when I'm on a roll programming and this has saved me a few times already. The only reason I didn't give 5 stars is because only 1 side runs on the battery back-up, but all of the ones I seen in this price range were like that.
