    Real Easy to install takes up very little space, haven't had the power outage yet to "test" it, but have great confidence it will work great

    Works really well an I love that it has the battery saver so that you won’t lose important information incase of a power surge. This is the second one I bought.

    We're using this little UPS to protect our cable modem, router and network stuff. We've already taken a few power hits and our network stayed up with no problems.

    Great product. Have used these brand before and it finally gave out over 7 years or owning it. So decided to buy the same brand. Seems to be smaller in size but works great.

    Not much else to say really. I have always had good luck with Cyberpower UPS's. You just have to make sure you choose the right size UPS for the equipment you want to keep running when the power goes out.

    We have power flickers a lot, and it restarts the router every time, which makes working from home a pain. This keeps the router running during the flickers, so no down time.

    I plugged my internet/cable router into this. Protects from the occasional/short power interruptions that would normally cause a reset. If you purchase one, it does take a few hours to charge up before putting into use.

    Bought for having to work from home and potential data loss, not needed to “use” it yet, but feel secure in knowing I’ll have a few minutes to safely shut down with out data loss.
