    These are great for preventing blackouts. They are working great so far and I have multiple outlets for my other electronics.

    I like it in the beginning, because of the battery is good when the lights are gone, and you have extra power to at least turn off your device, but start making a noise once in a while, like a beep.

    Not sure how to rate this device, as I really need power outages to judge it. That being said, soon after I plug in my new Cyber Power we did have a snapping power bump. Before this, my computer would have shut off and restarted...if the power was not out. This was an older Cyber Power that was definitely passed it's prime. My new Cyber Power surge protector did not blink. No restarting of the computer. For longer outages, well, luckily I have not had the chance to evaluate the CP.
