    I have yet to actually have a real power outtage, so other than manual breaker flipping, it hasn't really been put through its paces yet. That said, it seems to work as advertised without any glitches.

    A bit costly but I think it's worth it. Just got a new PC and my area has the occasional power loss for a split second. saved a shutdown within a week of buying it. prevents data loss and possible damage from losing power and possibly even acts as a barrier for lightning strikes. My pc runs a peak of 650w to 700w with a 850w power supply, not a fan of maxing out ratings and same for a BUPS. very happy with my purchase
