    There is nothing more annoying than having the internet drop because of subsecond power blip. My work is mostly connecting to customer remotely - very annoying when the connections drops and the long wait for everything to recycle. This is far bigger than my modem needs but it will keep it up for 2 to 4 hours - that is a lot of billable work time. Sometimes the power outage also takes the internet - nothing I can do about that. But last apartment the whole complex lost power (over 300 units) except me I had internet, TV and my computer equipment working for almost 2 hours before power restored. That one outage paid for all 3 of my back-up units. Never have a home without one.

    Affordable, and keeps both my work setup and gaming setup powered and secured against damage. Have had 2 power outages since purchasing and was able to work through my day uninterrupted, well... save the lack of wifi, but gave me time to build precious reports and ensure no data was lost.

    Decent sized for the price and good number of outlets. I like the overall design and it tucks away nicely. Otherwise does what’s it’s supposed to.

    The item preformed as it is designed to. Shortly after its purchase we lost power in a storm, but everything plugged into it stayed on. I love it.

    The CyberPower is supplying backup protection to a MacMini and peripherals. The battery provides sufficient battery life (approx 35 minutes) to power down devices. It has handled surges and power shocks will so far. The foot print and placement of plugs was a factor in my decision.
