    Useful back up battery system. Tested it and had plenty of time to do proper shutdown when power was abruptly cut off.

    I started buying CyberPower after several deceptions with the direct competence. As any CyberPower unit, it does the job perfectly but remember, the batteries, regardless of usage, do not last more than a year or year and a half. The good thing about this units is how easy is to replace the batteries and the cost is inexpensive (compared to the competence).

    Insurance that I hope I never need, but it seems to be more than capable.

    Needed a small UPS for my crockpot. When power flickers it would reset itself and ruin what I was cooking. This UPS fit the bill.

    REplacement for an older unit. It performed ok, the older one seemed a little more durable. In the summer months, we seem to get more spikes and such. This new unit shuts itself off more than the older one. I guess thats what it does, the equipment attached is safe and thats more important.

    Need to keep the routers up during power blinks and summer storms this is what you need. Works great for the router, modem, security system etc. mounts to the wall easily or on the under side of a shelf or just sitting on the shelf behind all the gear. Keeps everything running through uncertainty.
