    So far no problems, which is what I want. Since it is new, I am hoping it works should we ever have a surge.

    Easy purchase and pickup. Had to replace an older backup system. This unit is smaller and lighter however just as powerful. Good configuration on the plug ins. Price is fair.

    Software determined the choice

    Build quality is very good. USB outlet is useful, setup was simple, but the reason I chose this over the 450VA unit, which would have supplied all the backup power I need, is that PowerPanel software is available for it. This software has a well-designed user interface, and I find it was worth the extra money.
