This unit and its many features have saved my computer and peripherals many times over! I live in an are plagued by numerous power outages and brownouts that could have reaked havoc with my computer and its peripherals, had I not had them connected to this APC UPS. I also like the "Green" features of the unit as well as its many other features, like surge protection, back up so I can shut down my computer and peripherals during a power outage, lots of outlets, etc. The management software that accompanied the unit has allowed me to know when each time the power was compromised so I could report it to the power company. The only thing I wish could be improved would be that the records of outages would show up as individual events and not just the last event with a total of time on the UPS for all events within the selected time period. I am VERY satisfied with this unit and would recommend it to anyone!
