Title: Multiple failed units
Review: I have total 9 units. After just about a year, these things start shutting off randomly and eventually fail one by one. All devices connected to the UPS will suddenly get cut off from power; this is very bad for hard drives! Four (4) of these have failed so far completely and pretty much in the order that I have purchased them. I should have checked the reviews on Amazon.com I guess! I'm replacing these one by one with CyberPower as they seem to have better reviews around here.UPDATE: Indeed all 9 have failed eventually in very similar ways (blacking out randomly at first and then going away completely) after about a year. I've no problems on CyberPower units.
