    Works great as long as you’re not using a printer

    This thing is perfect for my work station as long as I don’t have my printer plugged into it. When the printer is plugged in it beeps (loudly) over and over every time you print. Apparently the surge of power is more than it prefers.

    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.

    No, I would not recommend this to a friend
