I bought this UPS because I live in Tucson where we get storms every summer with frequent lightning, and I also happen to have my computer in a room with that doesn't have the best quality electrical wiring. This combination makes power flickers and surges a daily occurrence, which wreaks havoc on my power supply and components, so I wanted a quality battery backup and power conditioner so I wouldn't have to worry about my investment being fried. The OmniSmart 1500VA does all that and more, with a long battery run time so I can safely shut down, and enough juice to power a system with multiple monitors, a power-hungry graphics card, and a large array of storage drives. The only negative I have encountered so far is that the software console (PowerAlert) can sometimes be unresponsive in that it shows my device as 'inactive,' when it clearly is functioning and fully charged.
