    Got this last minute when Hurricane Dorian was about to hit South Florida. I still have it plugged in and use it as a extension cord. So far so good!!!

    I was able to completely save and shut down during a power failure due to having this back up. Whew! A whole lot of work was saved from eternal loss.

    Perfect option for modem backup when the power goes out. Gives you enough time to shut down your work before you lose it.

    this was a Christmas present for my 10 year old grandson to protect his electronics. He was really impressed the amount of plugs he could put in.

    Recent outages, some lasting from a few minutes to several hours, cause me concern for my newly acquired all in one. It has no auto shut down functions, but will give you time to manually close-out and shut down.

    Great product. Cyberpower makes quality stuff. I wish I had checked at Costco first, as they had the same price for the next-step-up product (680VA versus 450VA or some such). Still happy though.

    Working great! Always use a Battery Back-up for our computers and printers. Insurance in case of power failure or a power surge.

    Does what it is advertised to do. A review this early is less meaningful. Hope to do one in 2 years
