Bests & Worsts Reviews from Amazon

APC does not tell you that some very important features are stripped from this unit (BE550G). The PowerChute software which works with APC UPS normally displays the output load (i.e. how many watts are being drawn by the devices which are connected to the battery-backup outlets) and also the estimated battery time at this load. However with the BE550G this information isn't provided on the "Current Status" screen - all you will see is two blank lines near the bottom of the page. So you essentially have zero visibility into how much battery capacity you're using and how long your equipment would stay powered up during an outage. I don't really see the point of having a UPS if I can't size it & my load to figure out how much runtime I'll get during an outage. I called APC support and they were initially puzzled by this problem. After asking around, the tech gave me the bad news that current load & backup time information wasn't available on the "models below the BE750G" although I didn't really get a clear answer as to whether or not this problem affected the BE750G as well. If you're not planning to connect this unit via USB to a PC and use PowerChute, then this problem won't affect you; but I'll be returning it and buying a Tripp Lite instead.
