    I bought two of these. One replaced an old unit and the other I got for a spare. They work and have good capacity for a small size.

    Great backup power supply. I use it on my satellite receiver and TV so it does not reset when the power is disrupted

    I'm not satisfied with cyberpower anymore. They seem to stop working soon. I have found that APC works much better, APC cost more but worth it!

    Easy to set up. So far it has been working fine. Only complaint is that the direction of the sockets limits the number of devices because many have large plugs.

    WARNING!! DO NOT BUY!!! This is the 3rd UPS I ever bought. The first 2 were APC and I never had a problem with them at all. For years the APCs performed flawlessly. That's why I LOVE APC!! This time I figured I would try a cheaper brand since it's just to power little modem and router in next room. Wow, what huge a mistake! This thing runs out of power within 3 minutes now, and it's not even 1 year old. When I first got it, it would stay on for about an hour or more with just the modem and router. Good thing I got the extra coverage, I'm taking it back tomorrow and getting an APC with the in store credit.

    I bought this to replace an older UPS. I've had one power outtage since I bought it and it gave me time to shut my computer down without losing what I was working on.

    Lots of positive reviews about this UPS, and it’s warranty. Will see in a few months and if I like it, I’ll switch all my UPS units to CyberPower.

    This thing is a game changer. I was having random reboots because of low power spikes. This thing keeps the power even and is just awesome.
