    Doesn't handle the power draw demands from a Mac Pro at startup well, but does just fine after everything is running. My APC 550VA never stumbled at startup like this does (gives alert that there's battery drain occurring during startup), but the Mac Pro starts and then has no issues thereafter.

    We’ve had it for less than a month. Power went out during the recent winds. It turned off. It did work when we turned the power off manually a week before for some work, so no clue why it stopped this time. Gonna have to exchange it.

    I bought this because I would have power outages and wanted to protect my electronics. So far its helped save my electronics from some power outages I've had. Also it notified me when I was overloading the unit. So in all it was a great purchase. I got it on sale too.
