This is not a glamorous product - it just sits there under my desk doing its job. But it does its job. I live in an area with lots of lightning storms, sometimes with short power outages, and that is what this product is for. I have not had damage to any equipment that was plugged into this product, and in terms of battery backup, I often realize that there was a very short power outage due to the beep from the UPS rather than from lights blinking or the like - in other words, it response very quickly. Of course it is a "550" with limits on its UPS capabilities, but I got what I paid for and more. It is what I needed. I am very pleased.

I use this battery for my 82" TV. We have lots of power interruptions in Florida and this battery keeps the TV running.

I've been using APC products for many years. Since I traded in the prior unit for the current model, there haven't been any blackouts or monster power surges but I expect it will eventually save my bacon as its predecessors have.

Have five of these installed. Perfect compromise between high end coverage (often over-kill) and cheap surge suppressors. Trust APC, love their trade-in process. Keep up the good work!

This the fourth APC Back-UPS that I have purchased. They have always performed flawlessly through storms and power outages. For some reason we have short intermittent power outages at various times of the year so instead of having to fire up the computer again or lose the page or site you were working on when their is a power blip it just switches over to the battery. Also protects against power surges to protect against any fried computer components.
