    When the storms come that knock trees into power lines, the electricity will frequently drop out for only seconds at a time. It wreaks havoc on fine electrical equipment. For a very reasonable price, this backup bridges the gap between the loss and restore of those brief outages. My particular use is for my UV water purifier for my well water. It prevents the early demise of an expensive UV bulb. The price of this backup is WELL WORTH not buying new UV bulbs all the time.

    Performs as expected for a UPS. This one (the 450VA) is a no-frills version - no display, no AVR (which I do think is important depending on what is being protected), and no USB ports except for the one that connects back to the PC for monitoring. It's a good one to catch, especially if you can find it on sale.

    Areogardens shuts down with brief power failures and require human intervention to restart. This backup has prevented a shutdowns, when I have been away from home keeping my plants from dying.

    Needed a small UPS to cover the power drop between outage and the generator coming online. Also the smaller size made mounting it easy.

    Easy set up. Haven't had a power outage yet but I ran a quick test and it worked as advertised. There are longer lasting solutions but this works for me at the price point.
