Title: Great product, but one major annoyance
Review: This product works very well and enables you to work through brownouts and blackouts, but it has one major nuisance: Every time the backup battery is activated, an audible alarm goes off and repeats every 5-10 seconds. The only way to disable it is to manually press the mute button each time the power goes out. If you have 2-3 of these around the house and you're in the middle of a storm, you're likely to go nuts running around the house muting the alarm all the time.
