    Works well. This unit is very compact, but still provides ample space for plug in transformers. Installation went smoothly without any issues.

    Fantastic UPS

    Love this UPS. It is practically silent (unlike some other brands) and the outlets are well spaced to allow compatibility with most plugs without blocking outlets. I strongly recommend doing your research in advance of purchasing to understand how long any UPS will support your connected devices on battery backup. Misunderstanding UPS abilities is the most common mistake made by purchasers of UPS systems.

    This works great, it keeps my modem and router running during power outages for hours though. It does beep whenever the power is out though. It could be i just don't know how to disable it, but its really not a big deal.

    This is pretty good for the cost. The battery itself isn't the longest lasting if you're have a lot of high draw equipment running on it; but it does give a decent enough buffer to safely turn everything off in the event of a power outage.

    Use a couple of these to keep the network routers up and running. No problems so far. Purchased on sale, so that always makes a difference.

    Got this to use for my cable modem, which I have to keep on the opposite side of my room to where my network stack is. No issues thus far, still haven’t gotten into storm season yet. Should be ok for light load power continuity
