    My previous CyberPower battery backup just died. I'd had it so long I can't remember when I bought it. It has protected my computer without any issues. So I definitely feel it was worth it.

    I've always had a UPS on my computer systems and this one works great. Protected my daughter's computer during the snow storm in Texas in March. Well worth the price!

    A perfect fit for two light use computers i have running. This is my second purchase of this product. The other one runs a few tv's and worked as intended during a power outage. So giving it a try on the computers. About a month in and the power went out again during a storm. The computers were unaffected for the power flicker. Great product. Always check your power needs vs what the battery back-up is rated to handle.

    So far, so good. Had to replace my old battery backup when it went on the fritz. This has many more outlets and sits very flat.

    This is a great battery backup. My favorite part it comes with a USB cable to plug into your computer. You can configure when to power off your computer safely in case of an outage.

    What can you say about a UPS? It works, it's cheaper than APC and well built. Has USB ports. The outlets are spaced well to handle chargers, etc.

    Great power outlet/ backup!!! Never have had to use the back up feature yet... But having the extra outlets and the added benefit knowing I have extra power after power outages is great.

    The whole point of the unit is to power your electronics and stop a surge. This is all I turn on so if it has worked I don’t know but my stuff still works. So I guess it’s working.

    This plug bar is designed well to accommodate plugs with different widths. The battery back up is extremely valuable during the many power outages we have in SOuth Florida.
