    Works like a charm. We use it to keep our internet up during frequent power glitches due to electrical storms. The flicker of power used to cause us to drop internet and force the modem to reconnect (10 min of downtime minimum). Now the connection stays steady.

    Whats to say? You want a good UPS to provide clean power to your devices, and CyberPower UPS units fit the bill perfectly. Don't just trust your expensive electronics to just plugging them into wall outlets, extension cords, or plain surge protectors!
