    Easy to use. I hooked up my router and modem so it doesn't reboot when the electricity goes out for a few minutes.

    I bought this after my old backup died. After using the CyberPower for 9 months I have had no issues. Just plug in and go. Great!

    Great add on to entertainment system. Lost everything to a power surge before buying this. When power goes out, it gives you enough time to make sure every is properly shut down.

    This is perfect for my needs. I have frequent dips in power. I have my desktop, router, phone charger, and laptop charger connected to this. It provides a clean voltage and gives me a chance to save my work and shut down when the power does go away.
