    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.

    I bought this item when recently a cheaper power surge protector's alarm went off. Freaked me out. Got this for my cable, TV, modem and router as well as PC & monitor. And so far, no issues. LOVE IT!

    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.

    I like this UPS. I install my new computer on it and others devices. For my internet modem and router I install it on the battery side and the computer on the side that does not have battery backup.
