Title: Good while it lasted. No warning of failure.
Review: I've had this unit for 3+ years and it seemed to work well. However, recently it just fails during even minor power events and my equipment goes down hard. No battery or error warning on the display. It just doesn't work anymore. I would not buy again. Power protection equipment is supposed to self test and warn you if the circuitry or battery has failed. I'm going with a known, reliable brand going forward.
